Potassium Octacyanomolybdate Synthesis

SYNTHESIS OF THE COMPOUND

1. 11.49 grams of sodium molybdate dihydrate are dissolved in 13.85 mL of water.
2. 34.62 mL of conc HCl are added dropwise from a dropping funnel with constant stirring.
3. The entire mixture is heated on a steam bath as 20.77 grams of potassium thiocyanate dissolved in 20.77 grams of water is slowly stirred into the hot liquid.
4.  The blood red solution is heated on the steam bath in the hood for 2 hours with frequent stirring. 
5. The liquid is suction filtered while hot to remove a black byproduct.
6. The filtrate is cooled in an ice bath and 9.69 mL of pyridine is added slowly with good stirring from a separatory funnel.
   1.   A red oily layer soon precipitates that becomes very viscous in the ice bath.
7. The supernatant is decanted and the oil is rinsed twice with two 7 mL portions of cold water.
8.  A solution of 27.70 grams of potassium cyanide dissolved in 41.56 mL of water is added to the oil. The reaction produces "cyanotic gasses".  
   1. The oil dissolves rapidly to give a green and then a yellow-brown solution. 
9. Heat the yellow-brown solution on the steam bath for 30 minutes with occasional stirring. 
10. The solution is suction filtered to remove a black material.
11. The solution is evaporated on the water bath to one half its original volume.
12. The solution is chilled in ice to precipitate the crude product which is filtered off and retained for purification. The filtrate is retained separately for further treatment.

PURIFICATION OF THE SOLID 1

1. The yellowish-black crystalline solid obtained in step 12 above is dissolved in a minimal amount of boiling water.
   1. A black product remains behind.
2. Five grams of decolorizing charcoal are stirred in for about 5 minutes.
3. The hot material is suction filtered and cooled in ice.
4. Two volumes of ethanol are added and crystallization is completed by allowing the mix to sit in ice for 30 minutes. 
5. The crystals are filtered off, rinsed with two portions of cold ethanol and then one portion of ether to facilitate drying. 
6. The crystals are dried in air. Yield is approximately 11.08 grams.

PURIFICATION OF THE SOLID 2

1. The solid is treated as above but the filtrate is treated with a faintly acidified solution of 19.39 grams of CdCl2•2.5H₂O in 27.70 mL of water is added slowly. When no more yellow cadmium octacyanomolybdate precipitates out discontinue adding the cadmium chloride solution.
2. The solid is filtered off, rinsed well with 15 mL of hot water and the same amount of alcohol.
3. Dry the solid in warm air.
4. Treat the solid cadmium octacyanomolybdate as described below in steps 6-17 to recover the pure potassium octacyanomolybdate. 

RECOVERY OF PRODUCT FROM THE FILTRATE 

1. The filtrate obtained in step 12 is diluted to a volume of 70 mL and reheated with charcoal until it is gently boiling. 
2. Allow the solution to boil with the charcoal for 5 minutes and then filter while hot. 
3. A faintly acidified solution of 30.29 grams of CdCl2•2.5H₂O in 27.70 mL of water is added slowly. When no more yellow cadmium octacyanomolybdate precipitates out discontinue adding the cadmium chloride solution.
4. The solid is filtered off, rinsed well with 15 mL of hot water and the same amount of alcohol.
5. Dry the solid in warm air. 
6. The cadmium salt is mixed with 25 mL of concentrated aqueous ammonia and warmed gently until solution is complete. Add more concentrated ammonia if the solid fails to completely dissolve.
7. The solution is slowly added to a boiling solution of 14.29 grams of anhydrous potassium carbonate in 214.29 mL of water.
8. The mixture is stirred continuously on the steam bath for 30 minutes.
9. The precipitated cadmium carbonate is fitlered off and washed with about 10 mL of hot water. Retain the filtrate.
   1. The CdCO₃ is saved for recycling.
10. The filtrate is evaporated until all of the ammonia is driven off. 
11. The filtrate is then filtered again to remove any cadmium carbonate that has precipitated.
12. The solution is then evaporated down until it is 28.57 mL in volume and filtered hot if necessary.
13. 42.86 to 57.14 mL of alcohol are added to the solution.
14. The mixture is chilled in ice and stirred until the precipitated product is solid. 
15. The solid is filtered off and ground in a large mortar with a solution of 1.43 mL of glacial acetic acid in 21.43 mL of alcohol to remove adhering potassium carbonate.
16. The crystals are refiltered and rinsed with three 7.14 mL portions of alcohol until totally free of acid.
17. Dry the crystals in air.

Aqueous solutions of potassium octacyanomolybdate are decomposed by sunlight with the evolution of HCN. They first turn red and then a pale green. The compound loses its water of hydration at 110^oC.

6. Potassium Chlor-Ruthenate
   1. Potassium Chlor-ruthenate, K₂RuCl₆, may be prepared by adding hydrochloric acid to potassium ruthenate.

Potassium chlorate is added little by little, and the whole stirred until all the ruthenium has dissolved. The heating is continued until evolution of gas ceases, indicating complete decomposition of the chlorate. On cooling, the orange-red-coloured melt is dissolved in cold water, and dilute hydrochloric acid added until the whole is slightly acid. Concentration is effected over quicklime until the salt crystallises out in reddish brown crystals. Potassium chlor-ruthenate may also be obtained by the action of chlorine on a concentrated, acidulated solution of potassium aquo-chlor-ruthenate, K₂Ru(OH₂)Cl₅. It then crystallises in minute black octahedra possessed of a greenish sheen, and which are easily soluble in and rapidly decomposed by water. In hydrochloric acid a pure yellow colour is obtained if the solution is dilute, the concentrated solution being deep yellowish red.

1. Preparation of Mercurous Nitrate
   1. 25 grams of mercury are treated with 20 ml of 6N (25%) nitric acid by warming gently until no further action takes place. The solution of mercury(I) nitrate is cooled, separated by pouring from any remaining globule of mercury into a small dish, and left to crystallize until the next day. The next day obtained crystals are spread out on a filter, covered with a paper towel and left to dry completely at room temperature. Mercury(I) nitrate is kept in a stoppered bottle as soon as it is dry. Mercury(I) nitrate obtained by described method contains one molecule of water (mercury(II) nitrate monohydrate). Synthetic Inorganic Chemistry by A. Blanchard, page 232.
2. Potassium Platinocyanide
   1. Potassium Platinocyanide or Gmelin's Salt, K₂Pt(CN)₄•3H₂O, was the first platinocyanide to be discovered, namely, by Ittner, who allowed mixed solutions of potassium cyanide and platinic chloride to crystallize. Ittner, however, does not appear to have understood the nature of the compound he had prepared. Gmelin, who discovered the ferricyanides, observed that by heating to redness a mixture of platinum sponge and potassium ferrocyanide, a compound results in which platinum replaces iron. Analysis of the product crystallized from water showed it to have the formula K₂Pt(CN)₄•3H₂O, when translated into modern symbols.

11. Barium ferrocyanide = K ferrocyanide yellow
    Cobalt ferrocyanide = Paris Green
    Copper ferrocyanide = brown An interesting experiment consists in preparing in a gas jar a saturated solution of copper sulphate and diluting some 50 per cent. A drop of saturated potassium ferrocyanide solution is now introduced by means of a pipette and rapidly sinks to the bottom of the jar. It does not mix with the copper sulphate solution, for its surface which came into contact with the latter solution is now covered with a thin and invisible membrane of copper ferrocyanide. After lying at the bottom of the jar a little while, the drop will be seen to increase slightly in bulk, and then rise up through the copper sulphate solution to the top of the jar. This is due to water passing through the copper ferrocyanide membrane and reducing the density of the potassium ferrocyanide solution.
    Manganese ferrocyanide = white substance which is turned green by chlorine water and oxidised to brown ferricyanide by bromine water. 
    Nickel ferrocyanide = bluish green in colour

    Silver ferrocyanide = white precipitate by double decomposition of a silver salt with potassium ferrocyanide. With nitric acid it yields orange-red silver ferricyanide.
    Cobalt ferricyanide = red
    Mercurous ferricyanide = is obtained as afloceulent cream-coloured precipitate on the addition of mercurous nitrate to potassium ferricyanide solution. It turns blue on exposure to air.
    Mercuric Ferricyanide = bright yellow may be obtained by adding a concentrated aqueous solution of potassium ferricyanide to a solution of mercuric chloride in alcohol and ether. The precipitate is bright yellow in colour, and fairly stable when dry.

27. Thallium(I) Tribromotrichlorothallium(III) Tl₃[TlCl₃Br₃]
    1. It is also said by Cushman to be produced by boiling a solution of thallic chloride with thallous bromide and cooling, or by boiling a solution of thallic bromide with thallous chloride. It is also produced when a limited quantity of bromine is added to thallous chloride suspended in cold water, the yellow solid produced dissolved in boiling water, and the filtered solution slowly cooled. The filtrate from the deposited crystals, when concentrated and cooled, deposits more of the compound Tl₄Cl₃Br₃, in six-sided plates, but mixed with needles of the compound Tl₄Cl₄Br₂.

Synthesis of Hydriodic Acid (Uncle Fester's Secrets of Methamphetamine Manufacture page 160, paragraph 2)

1. To then use the iodine, one first puts the mixture into a large sep funnel. Add a couple hundred ml of toluene and shake. The toluene will dissolve about 40 grams of iodine. Separate off this toluene solution.
2. In the example batch given in this section, we are using 300 ml of water and 30 grams red P.
3. Add the toluene to the 300 ml of water and 30 grams of red P.
4. Then shake to react the iodine with the phosphorous. Keep the mixture cool.
5. Then separate off the toluene from the water/Hi mixture.
6. Wash it with a 300 ml portion of water which will be used in the next batch. This will remove HI from the toluene, and save it for the next batch. Finally, pour the toluene back into the sep funnel with the iodine and shake to get another load of iodine. One repeats this process until all the red P has been consumed.

2NH₄C1O₃ + Ba(OH)₂•8H₂O → Ba(ClO₃)₂•H₂O + 2NH₃ + 9H₂O
 

1. A mixture of 122.6 g. of potassium chlorate, 70g. of ammonium sulfate and 350 ml. of hot water is evaporated in a porcelain dish with constant stirring until a thin slurry forms.
2. After cooling, a fourfold quantity of ethyl alcohol is added, resulting in the separation of insoluble potassium sulfate from the ammonium chlorate.
3. The potassium sulfate residue is filtered and washed several times with alcohol.
4. The filtrate is freed of alcohol by distillation.
   1. Come up with an alternative method. Distillation can be done part of the way under vacuum at low heat but after that a gentler way should be found. 
      1. Experiment with small quantities of the concentrated solution to figure out what is and isn't safe.
      2. Further reading and video watching on the properties of ammonium chlorate should be carried out. 
5. The ammonium chlorate residue (caution: ammonium chlorate has a tendency to explode!) is reacted in a porcelain dish on a steam bath with a sufficient quantity of hot concentrated barium hydroxide octahydrate solution (at least 160 g. of barium hydroxide octahydrate dissolved in about 160 ml. of hot water) so that the ammonia odor disappears completely and the solution finally gives a definite alkaline reaction. It is then evaporated to dryness. The residue is dissolved in a fivefold quantity of water, and carbon dioxide is bubbled through the solution until the precipitation of barium carbonate is completed. The barium carbonate is filtered off and the solution evaporated to crystallization.

Barium Chromite, BaCr₂O₄, is obtained as a dense green crystalline powder by heating a mixture of potassium dichromate and barium chloride to redness. By heating together chromium sesquioxide and barium oxide in the electric furnace a polychromite, BaO.4Cr₂O₃, is produced, even when excess of baryta is present. It forms a greenish-brown powder of density 5.4 at 15° C.

Barium Chromate, BaCrO₄, is obtained as a pale yellow powder of density 4.3 – 4.5 by precipitation from solutions of a chromate and a soluble barium salt. It can be prepared in the form of rhombic crystals, isomorphous with barium sulphate and of density 4.6, by fusing sodium and potassium chromates with barium chloride.

Barium chromate is stable at red heat, and for that reason has been employed in painting porcelain. It is practically insoluble in acetic acid, but is readily dissolved by hydrochloric, nitric, and chromic acids. It is decomposed by sulphuric acid and by a hot solution of sodium carbonate. In the latter case a definite equilibrium point, between barium chromate and sodium carbonate on the one hand, and barium carbonate and sodium chromate on the other, is reached.

The solubility has been determined by electrical conductivity methods.

Temperature, °C	-0.88	16.07	17.42	18	28.08
Mgm. BaCrO4 per litre	2.04	3.37	3.48	3.52	4.36
Milli-equiv. per litre	0.0161	0.0266	0.0275	0.0278	0.0344

Barium chromate is soluble in molten sodium nitrate. By precipitation from concentrated solutions a barium potassium chromate, BaCrO₄.K₂CrO₄, and a barium ammonium chromate, BaCrO₄.(NH₄)₂CrO₄, may be obtained.

Barium Dichromate, BaCr₂O₇, is obtained by heating together solid chromic acid and moist, freshly precipitated barium chromate mixed with potassium chromate and potassium dichromate, or by boiling freshly precipitated barium chromate with chromic acid and nitric acid, or, finally, by decomposing the chromate with dilute sulphuric acid. It crystallises in slender, yellowish-brown, rhombic prisms as BaCr₂O₇.2H₂O, the 2 molecules of water being lost at about 100° C. Barium dichromate is decomposed by water, giving the chromate.

By treating chromic acid with an excess of hydrogen peroxide and decomposing the liquid obtained by cooled barium hydroxide solution, a very unstable, pale yellow-coloured precipitate of the Barium Perchromate, BaCrO₅, is obtained. It may be washed by decantation and dried over sulphuric acid in vacuo. It is detonated by heat or shock. With dilute sulphuric acid it turns blue and gives up oxygen.

Sunday, December 8th, 2019    I have gotten to know ruthenium much better and it's turning out to be quite a remarkable element. She (yes, ruthenium is a she) has so many damn stable oxidation states and it makes the chemistry of this element so unexpected. If osmium acts like this I can see why he is so popular in organic synthesis. Ruth and Ozzy are quite the pair although she's not nearly as evil as he is. Osmium is the only element I flat out refuse to work with. He has a ridiculous tendency to form a gaseous tetroxide that could double as a war gas (in fact a terrorist plot to blow up a bomb loaded with OsO4 was stopped in 2004 in the UK). Ruth also has a very nasty tetroxide but she has less of a tendency to go Full Tetroxide on your ass and her tetroxide isn't as stable as Ozzy's is.

So first of all when I precipitated yesterday may or may not have been ruthenium hydroxide. I THINK that it was a hydrated form of the dioxide which passes as the hydroxide. I am honestly not sure. Ruth has so many fucking stable oxidation states that it's really hard to know what is going on. Anyways I reacted that with HCl to obtain a dark red solution and not the yellow one I was expecting. I had no idea what the hell happened (I'm still not quite sure) but when I tried to reduce it back to metallic ruthenium with borohydride I instead got a bright red perfectly clear solution. I thought it might be Ru(III)Cl3 but after trying to do some double salts that all failed I am not sure what the fuck it was. I am going to re-do the entire series of operations on video and I will see what feedback I can get. There are a lot of great chemists who do work on YouTube and who are better with inorganic than I.

Oh I finally did get the solution to reduce back to metallic ruthenium after I made it alkaline. At least I think it did. It turned a mocha brown (like coffee with creamer in it but thicker) and then a very dark brown and then black. I put it in a jar to settle out overnight so we will see if it reduced back to metallic ruthenium or some other compound. I don't know how I am going to recycle this shit. I have to avoid the tetroxide at all costs so calcination is out. Ru doesn't form the tetroxide until like 1000 C but I don't know if that's only bulk Ru. I have a super fine precipitated powder. At $19 a gram and given how far 1 gram will stretch it's probably cheaper and easier to just order more ruthenium than to try to recycle a lot of this waste. WTF am I going to do with it? Even if I reduce it the particles will be stuck to all the fibers of the filter papers and I don't dare try to calcine or chemically decompose those fibers for fear I will produce RuO4. I REALLY need to talk to someone who has worked with this shit and who knows more about it than I do. I feel like I'm walking down a very dimly lit hallway in which I know somewhere there is an open well but I don't know exactly where it is, what side of the hall it's on, and what side I need to walk down to go around it working with this shit.

From Tony Manicus: By adding sodium chlorate and sodium bromate at pH 1 will increase the pH to around 5.5 will also form RuO4. Bisulfite will reduce ruthenium tetroxide to the much safer dioxide (Oxidation of Primary Alcohols to Carboxylic Acids: A Guide to Current Common Practice. Gabriel Tojo and Marcos Fernandez, page 61).

The following data is taken from atomistry.com articles on the chemical compounds of ruthenium. The main sub-page for this topic is linked below and the compounds are indexed on the left hand side of the screen. Other references are credited as they are shown. 

1. Chemical Properties of Ruthenium
   1. When heated in air ruthenium becomes covered with a brown film of oxide and, on cooling, "spits" in a similar manner to iridium and silver. Heated in oxygen, particularly when in a fine state of division, it yields the dioxide, RuO₂, and at 600° C. some tetroxide, RuO₄, begins to be formed. Previous ignition in hydrogen to a high temperature reduces the velocity of oxidation of ruthenium. Mineral acids have no action upon ruthenium, and aqua regia only slowly dissolves it.
      1. Ruthenium reacts very little oxygen, O₂, under normal conditions. If heated, ruthenium is oxidized to Ru(IV) oxide: Ru(s) + O₂(g)  RuO₂(s) Michael Pilgaard's Elements Website
      2. When molten, silver occludes the oxygen of the atmosphere, absorbing 20 times its own volume of the gas; the oxygen, however, is not permanently retained, for on cooling it is expelled with great violence; this phenomenon is known as the "spitting" of silver. It is prevented by preserving the molten metal from contact with air by covering the surface with non-oxidizing agents, or by traces of copper, bismuth or zinc. From Theodora.com article on Silver
      3. It IS soluble in aqua regia! Hooray! But what what is the product of that reaction?
         1. If potassium chlorate is added to aqua regia, it will oxidise ruthenium explosively. Google Search
      4. Most ruthenium compounds decompose to metallic ruthenium when heated sufficiently or when reduced with hydrogen. Google Search
   2. When heated in fluorine a volatile fluoride is formed, and in chlorine a chloride is obtained, possibly the dichloride, RuCl₂. Ignition with potassium chloride in a current of chlorine yields potassium chlor-ruthenate, which is soluble in water.
      1. When heating to 330 °C, ruthenium will react with chlorine, Cl₂, in the presence of carbon monoxide, CO, forming a dark brown ruthenium(III) chloride, RuCl₃. Additional heating of the material, in the presence of Cl₂, gives a black form of ruthenium(III) chloride. Ru(s) + 3 Cl₂(g)  2 RuCl₃(s) Michael Pilgaard's Elements Website
      2. Potassium Chlor-ruthenate, K₂RuCl₆, may be prepared by adding hydrochloric acid to potassium ruthenate. Atomistry
   3. Alkali hypochlorites effect the solution of ruthenium when fused, but the best mixture to employ consists of potassium hydroxide and nitrate, a green mass of potassium ruthenate, K₂RuO₄, being formed. This dissolves in water to an orange-coloured solution, which leaves a black stain upon the skin.
      1. Addition of aqueous barium acetate will precipitate barium ruthenate BaRu(VIII)O₄ as a dark, brick red powder. 
         1. Will addition of HCl to barium ruthenate produce barium chlor-ruthenate, BaRuCl₆ leaving a residue of barium chlor-ruthenite BaRuCl₅? 
   4. Fusion with potassium hydrogen sulphate is without effect upon ruthenium, although in like circumstances rhodium, palladium, and iridium are attacked.
      1. Platinum is slightly attacked by fused alkali carbonate, more so by the fused nitrate or hydrogen sulphate, and strongly attacked by fused hydroxide or peroxide. Atomistry
      2. When fused with potassium hydrogen sulphate, rhodium dissolves, yielding the sulphate. This reaction is interesting as affording a convenient method of separating the metal from iridium and platinum. Atomistry
         1. Does platinum dissolve much more slowly than ruthenium?
2. Ruthenium(IV) Sulfate
   1. Ruthenium Sulphate, Ru(SO₄)₂, results when the precipitated sulphide is oxidised by solution in nitric acid,
   2. and by dissolving barium ruthenate in fuming hydrochloric acid, evaporating to dryness, extracting with water and adding excess of dilute sulphuric acid. The barium is precipitated and the filtrate is concentrated, yielding a red liquid, from which, however, Antony could not obtain the crystalline salt.
   3. It is also produced by dissolving the tetroxide in sulphuric acid. On evaporation the orange solution yields a yellowish brown, amorphous residue, which is very deliquescent and easily soluble in water.
   4. On warming with alkalies, ruthenium hydroxide is precipitated from solution.
3. Ruthenium(IV) Oxide
   1. Ruthenium Dioxide, RuO₂, is obtained as a sublimate by heating ruthenium in a current of oxygen. The metal may thus be extracted, along with osmium in the form of its more volatile tetroxide, OsO₄, from osmiridium by heating the last named in oxygen (or air) to about 1080° С. If the mixed vapours are passed through a heated porcelain tube ruthenium dioxide condenses first.
   2. If the ruthenium is finely powdered, the oxidation begins at 600° C. and increases rapidly with the temperature, being 4000 times as rapid at 1200° C. as at 700° C. Crystals of the dioxide may be detected in the sublimate. Previous ignition in hydrogen to a high temperature reduces the velocity of oxidation of the metal.
   3. The dioxide may also be obtained by heating the sulphate or disulphide in the presence of air. It crystallises in the form of hard, tetragonal pyramids, of density 7.2, and isomorphous with cassiterite and rutile. The crystals exhibit a green iridescent metallic lustre. They are not acted upon by acids, but (the crystals of ruthenium dioxide) yield potassium ruthenate when fused with potassium hydroxide.
      1. Great care should be taken heating ruthenium sulfides in air
   4. The dioxide undergoes partial dissociation at temperatures above 1000° C., and when heated in vacuo the oxygen tension amounts to 15 to 17 mm. at 1000° C., and a little metallic ruthenium remains behind on cooling beneath the layer of dioxide.
   5. Ruthenium dioxide is obtained in the hydrated condition, RuO₂.xH₂O, as a dark red precipitate by heating the sulphate with potassium hydroxide solution. On heating to 300° C. it loses water, and at higher temperatures deflagrates with incandescence. It dissolves in acids and alkalies to yellow-coloured solutions. Claus gave the formula Ru(OH)₄.3H₂O to the precipitate, but Gutbier and Ransohoff show that the composition is variable.
4. Ruthenium(VIII) Tetroxide
   1. Can be synthesized by...
      1. Bubbling chlorine gas through a solution of an alkali ruthenate and warming to 80-90 °C to distill.
         1. The tetroxide distills over and, on cooling, yields a golden yellow mass. It may be purified by repeated shaking with warm water to remove all traces of chlorine, separating as completely as possible from water, and finally subliming several times in vacuo, when it yields beautiful crystals melting at 25.5° C. to an orange liquid, and decomposing at 106° to 107° C., yielding the crystalline dioxide.
         2. The vapour vigorously attacks cork and rubber.
      2. By oxidation of ruthenium(III) chloride with metaperiodate or hypochlorite
      3. By oxidation with chlorate and/or bromate at low pH (so oxidation by chloric acid or bromic acid)
   2. Ruthenium Tetroxide, also known as Ruthenium Peroxide, RuO₄, results in small quantity when ruthenium is heated to about 1000° C. in a current of oxygen.
   3. Ruthenium tetroxide dissolves to a slight extent in water (2% w/v at 20 ^oC). It is also soluble in caustic alkali, from which solutions a black precipitate of finely divided ruthenium is obtained on addition of alcohol. In contact with alcohol the solid tetroxide is reduced with explosive violence.
   4. Both the aqueous solution and the pure substance itself possess an odour resembling that of ozone. Its vapour, however, is not poisonous like that of the corresponding tetroxide of osmium.
      1. Modern references hold both of these compounds to be very highly toxic and recommend handling both the same way. 
   5. When covered with water, to which a concentrated solution of caesium chloride is subsequently added and a little hydrochloric acid, ruthenium tetroxide is gradually converted into the oxy-salt, Cs₂RuO₂Cl₄. The corresponding rubidium salt has likewise been prepared.
   6. Ruthenium tetroxide is permanent when kept in sealed tubes in the dry state and protected from light. Exposed to light it assumes a brown colour, but. the brown product is soluble in alkali, yielding a ruthenate. Presumably the coloration is due to partial reduction.
   7. Owing to its ready reduction by organic substances whereby a black precipitate of finely divided ruthenium is obtained, potassium per-ruthenate has been found useful for histological microscopy.
   8. Several other oxides have been described, namely, Ru₂O₅, Ru₂O₅.2H₂O, Ru₄O₉, RuO₃, and Ru₂O₇. Of these, the first three are probably indefinite mixtures rather than separate chemical entities. The last two oxides do not appear capable of a separate existence although their compounds are well known. These are termed: Ruthenates, M₂RuO₄, and Per-ruthenates, MRuO₄
5. Potassium Chlor-ruthenite K₂RuCl₅ (Listed under the Ruthenochlorides M₂RuCl₅ article)
   1. This salt may be prepared by the reduction of ruthenium nitrosotrihydroxide, Ru(NO)(OH)₃, in alkaline solution by boiling with formaldehyde, dissolving in hydrochloric acid, and separating out the salt by addition of potassium chloride. Obtained in this way the crystals are brown in colour.
   2. The salt may be prepared in an impure form by dissolving ruthenium in fused potassium hydroxide, adding small quantities of potassium nitrate the while, until all the ruthenium has passed into solution. On cooling the green mass becomes orange, and treatment with concentrated hydrochloric leaves a residue of potassium chlor-ruthenite.
      1. The impurity referenced here is Potassium Chlor-ruthenate K₂RuCl₆
   3. A convenient method of preparing a fairly pure specimen of potassium chlor-ruthenite consists in adding freshly distilled ruthenium tetroxide to concentrated hydrochloric acid and digesting on the water- bath until evolution of chlorine ceases. This requires about two days. To the resulting strongly acid solution of ruthenium trichloride, potassium chloride is added in small quantities at a time, whereby a precipitate of crystals of potassium chlor-ruthenite is obtained. These are washed free from acid with alcohol, and dried by exposure over concentrated sulphuric acid.
   4. Potassium chlor-ruthenite rapidly hydrolyses in aqueous solution, the liquid, originally red, gradually becoming black. The velocity of the hydrolysis admits of determination by electric conductivity measurements in consequence of the hydrochloric acid set free. The equilibrium of the hydrolysed solution is not altered by dilution, by addition of acid, or by change of temperature. It thus appears that the reaction is irreversible, and that the final state does not represent a true equilibrium. The reaction appears to take place according to the equation : K₂RuCl₅ + 2H₂O = 2KCl + 2HCl + Ru(OH)₂Cl.
   5. Addition of alkali hydroxide to the hydrolysed solution yields an immediate precipitate of hydrated ruthenium sesquioxide, Ru₂O₃.3H₂O.

Thursday, November 21, 2019    I think I've got it. This would all be done in a large test tube (one of the good ones). I can sonicate the radium dials in water to remove the radium containing paint from the dials. Then after removing the dials by decanting I'd probably add a bit more water and sonicate again to make sure I got it all. Then decant again and combine the suspensions. Then it should be a simple matter to add a dilute solution of any of the phosphors in order to get a luminescent solution. I don't know how bright it would be given that it's the radium from 12 very small dials distributed throughout at least several mLs of solution but it might be enough to actually see or otherwise detect. 

If the radium is present as radium sulfate is soluble in ~70% sulfuric acid. If it's present as radium sulfide which I suspect it probably is since it's most likely combined with zinc sulfide then that is soluble in a whole host of acids even in the cold. Or barium sulfide is anyways. I couldn't find much information about radium sulfide but since radium and barium have such similar chemistries they should behave essentially the same. Barium sulfide is very soluble in nitric acid so perhaps a mix of sulfuric and nitric acids to dissolve either radium sulfide or radium sulfate would be best. I'd love to hear your thoughts on it. I think it could be done safely with no release of radium into the environment and steps can be taken to contain any accident if one occurs. And I would wear all the PPE for this one! I don't want to touch that shit!

The hexachloroplatinic acid produced by dissolving one gram of platinum into aqua regia was evaporated down in a 100 mL evaporating dish being reconstituted with 6M HCl every time it approached "dryness" (a gummy orange-red residue is all I got at first). These repeated evaporations removed the HNO₃ left over from the aqua regia. Then repeated evaporations with distilled water were carried out to remove all of the residual HCl. This process took about 12 hours stretched over 2 days.
2. The hexachloroplatinic acid is dissolved in 20 mL of distilled water. 
   1. 1 gram of platinum is equal to 0.005125997 moles of platinum. This gives a 0.256 molar solution of hexachloroplatinic acid.
   2. Hexachloroplatinic acid is 409.81 grams per mole
   3. 0.005125997 moles of hexachloroplatinic acid is 2.100 grams of hexachloroplatinic acid
   4. Divided into 20 portions of aqueous solution that would be 105 mg of hexachloroplatinic acid per mL of solution.
3. 1 mL of the solution is reacted with a stoichiometric amount of cesium chloride to produce Cs₂PtCl₆
   1. Molar mass of dicesium hexachloroplatinate is 673.6129 grams per mole
   2. 0.005125997 / 20 = 0.00025629985‬ moles = 0.17264 grams dicesium hexachloroplatinate.
   3. 0.00025629985‬ x 2 = 0.0005125997‬ moles of cesium chloride needed.
   4. Cesium chloride = 168.36 grams per mole. Thus 0.0005125997 moles of cesium chloride = 0.08630 grams of cesium chloride needed
   5. 3.308 M CsCl = 0.003308 moles CsCl in each mL of solution ⇒ 0.55693488‬ grams in each mL ⇒ 0.15495663 mLs solution needed. 
      1. 1:10 dilution takes the molarity down to 0.3308 M ⇒ 0.055693488‬ grams in each mL ⇒ 1.549552 mL needed
   6. Cool the resulting solution to ensure complete precipitation of the dicesium hexachloroplatinate. Dry and photograph the crystal film.
4. 5 mL of the solution is combined with an ammonium chloride solution which results in ammonium hexachloroplatinate. Decomposition of the salt by heating produces platinum sponge (do this to recycle platinum waste). ​​
   1. Addition of potassium chloride to "acidulated" hexachloroplatinic acid (presumably with a small amount of HCl) followed by cooling results in the precipitation of potassium hexachloroplatinate which is even less soluble in 85% ethanol. 
   2. Also used to produce "platinum black" by reducing ammonium hexachloroplatinate in a current of hydrogen gas at 100 ^oC. 
      1. 5 mL of the solution contains 525 mg of hexachloroplatinic acid which is 0.0012810 moles. 
      2. 0.0012810 x 2 = ‭0.002562‬ moles ammonium chloride needed
      3. Molar mass of ammonium chloride = 53.49 grams per mole
      4. 0.002562‬ moles ammonium chloride = 0.13704138‬ grams ammonium chloride
      5. 0.0012810 moles of platinum metal = 249.9 mg of platinum black suspended in liquid
         1. Atomic weight of platinum is 195.084
5. Weigh first!!! Bubbling SO₂ gas through 10 mLs of a solution of hexachloroplatinic acid maintained at 100 ^oC will produce tetrachloroplatinous acid. 
   1. The reaction is complete when the solution no longer gives a precipitate with ammonium chloride which is ammonium hexachloroplatinate.
      1. Add ammonium hexachloroplatinate produced in this way to platinum recycling. 
   2. Once the reaction is complete twice the calculated amount (the stoichiometric amount?) of potassium chloride in a hot aqueous solution is added and the solution is allowed to cool. Potassium tetrachloroplatinite crystallizes out. It must be kept out of the light. The solid is isolated by decanting the liquid and the solid is washed with alcohol. It must be dried in the absence of light. 
   3. The liquid decanted above is combined with two molar equivalents of sodium nitrite and then with two molar equivalents of silver nitrate. In theory this should result in the precipitation of Silver Platinonitrite when allowed to cool. If successful it will crystallize out in yellow monoclinic prisms. 
      1. Weigh the mass of the tube + the potassium tetrachloroplatinite crystals and subtract from starting weight. 
      2. From this calculate two molar equivalents for sodium nitrite and silver nitrate.
         1. Sodium nitrite = 68.9953 grams per mole
         2. Silver nitrate = 169.872 grams per mole
6. 2 mL of the solution is combined with a sodium iodide solution to produce platinum tetraiodide. 
   1. 2 mL of the solution contains 210 mg of hexachloroplatinic acid
   2. 210 mg of hexachloroplatinic acid is 0.0005124325 moles
   3. Molar mass of sodium iodide is 149.89 grams per mole. 
   4. 0.0005124325 x 4 = ‭0.00204973‬ moles = 0.3072 grams NaI needed.
7. 2 mL of the solution is combined with sodium selenite and KOH and then reduced with formaldehyde to produce platinum triselenide. 
   1. Add 2  molar equivalents of potassium chloride in hot aqueous solution.
      1. 0.0005124325 x 2 = ‭0.001024865‬ moles of KCl needed 
      2. KCl = 74.5513 grams per mole ⇒ ‭0.0764 grams KCl needed
   2. Add 3 molar equivalents of sodium selenite
      1. Sodium selenite = 172.948 grams per mole
      2. 3 molar equivalents is 0.0005124325 x 3 = ‭0.0015372975‬ moles ⇒ 0.2658 grams sodium selenite needed
   3. 9 molar equivalents of KOH are needed
      1. KOH = 56.11 grams per mole 
      2. 0.0005124325 x 9 = 0.0046118925‬ moles ⇒ 0.259 grams KOH needed
   4. 8 molar equivalents of formaldehyde are needed
      1. Molar mass of formaldehyde = 30.026 grams per mole
      2. 0.0005124325 x 8 = 0.00409946‬ moles formaldehyde = ‭0.12309038596‬ grams needed
   5. Change the PtSe3 to 1 mL of hexachloroplatinic acid solution.
      1. 0.0382 grams of KCl, ‭0.1329‬ grams of sodium selenite, 0.1295‬ grams of KOH, 0.06154519298‬ grams formaldehyde
         1. Density of 37% formaldehyde solution = 1.09 grams per mL at 25 ^oC
         2. 37% of 1.09 grams is 0.4033‬ thus each mL of solution contains 0.4033‬ grams of formaldehyde 
         3. 0.15260 mL of 37% formaldehyde is needed
         4. Make 1:10 dilution of 37% formaldehyde. 1.526 mL of 3.7% formaldehyde

(NH₄)₂Cr₂O₇ + 4NaOH → 2NH₃ + 3H₂O + 2Na₂CrO₄

1. Dissolve as much of 48.11 grams of ammonium dichromate in 95 mL of water as possible.  
   1. 100 grams of sodium dichromate is 0.3817230 moles. Cut that amount in half due to inventory limitations.
   2. 0.1908615‬ moles of ammonium dichromate is 48.11 grams.
2. Add dropwise with stirring a solution of 30.54 grams of NaOH dissolved in 30 mL of water. 
   1. 0.763446‬‬ moles of NaOH = 30.54 grams
3. Once all of the aqueous sodium hydroxide has been added the solution is heated to boiling and it is allowed to boil for a short time. More water is added if needed to keep the volume at 125 mL.

5. Concentrated sulfuric acid is added dropwise with stirring until a slight lasting precipitate of chromium trioxide is formed. A little more than 100 mL will be necessary as some of the sulfuric acid is consumed converting the sodium chromate to sodium dichromate. 
6. The mixture is then cooled in salted ice water for 30+ minutes.
7. 100 mL of concentrated sulfuric acid is then added dropwise to the chilled solution in order to fully precipitate chromium trioxide. 

1. PROTOCOL FROM PREPCHEM.COM
2. 100 grams of sodium dichromate are dissolved in 250 ml of water and the obtained solution is filtered.
3. 200 ml of concentrated sulfuric acid are dropwise added with constant stirring until a slight permanent precipitate of chromium trioxide is formed.
4. The mixture is cooled for half an hour or longer, then slowly, while stirring, 200 ml of concentrated sulfuric acid are added dropwise.
5. The reaction mixture is left to stand over night in order that the crystal meal may become somewhat coarser. The larger crystals (and purer) of chromium trioxide could be obtained by heating the solution with crystal meal with stirring to 100° C and allowing to cool slowly. If this process is repeated once or twice, a more satisfactory product will be obtained.
6. The obtained crystals of chromium trioxide are filtered with a Buchner funnel with a sintered glass disc instead of the usual paper filter (chromium trioxide is a strong oxidizing agent and will oxidize organic material).  
7. Drain the crystals completely and press the surface.
8. Treat with 15 ml of concentrated (65-70%) nitric acid. The nitric acid is removed by suction and the operation is repeated twice with 10 ml of nitric acid each time. 
9. Finally, the red crystals of chromium trioxide are dried by suction as much as possible, transferred in a dry evaporating dish and by gentle heating the remaining nitric acid is removed. Dried product is stored in a stoppered bottle. Yield is 60%.

I am working on improving my crystal growing and photographing techniques. I set up the desiccator with 3A molecular sieves like normal and then after the solutions on their watch glasses were placed in there and the lid closed up on it I put a heater right next to it and had it blow onto the desiccator. That raised the temperature in the desiccator significantly which drove complete evaporation of the droplets and the quicker formation of still very well formed crystals. I then had the heater blow directly onto the watch glass as I photographed the crystals. This produced GREAT crystal films for the solutions but there still wasn't enough heat to keep the crystal films from rapidly absorbing water. Stronger heating while taking the pictures is needed.

I need another good compound to do for the channel. I am going to work on getting that TLC protocol for indole alkaloids ready for filming. That will probably take a while. It's pretty involved. I bought a glass cutter to make my TLC plates stretch further. I am also going to need to make up a modified Ehrlichs's Reagent to visualize the spots and that is going to take some work all by itself. In the meantime I need to come up with another good compound I can film me making. Trying to find a good exotic inorganic that I haven't done yet but that I am able to do with what I have. 

I was thinking of maybe trying to see if barium iridate will form the same acetyl complex that barium ruthenate does. That could be cool. And if I make some pyridine I can make up a cool cobalt complex. I could REALLY use a stir plate!!! But none of that will be ready to do today so the next full length video is going to be some transition metal complex. Haven't quite decided which one to do but these are the candidates:

Another method, used especially for diiodides, involves heating the metal with HgX₂: Tm + HgI₂ → TmI₂ + Hg 

Praseodymium and terbium form higher oxides, of which a number of phases are known between Ln₂O₃ and LnO₂. Ignition of praseodymium nitrate leads to Pr₂O₃ but further heating in an oxygen atmosphere gives Pr₆O₁₁ or even PrO₂; terbium similarly yields Tb₄O₇ and TbO₂.

PrO_1.83 https://en.wikipedia.org/wiki/Praseodymium_(III,IV)_oxide

Although usually trivalent, ytterbium readily forms divalent compounds. This behavior is unusual for lanthanides, which almost exclusively form compounds with an oxidation state of +3. The +2 state has a valence electron configuration of 4f¹⁴ because the fully filled f-shell gives more stability. The yellow-green ytterbium(II) ion is a very strong reducing agent and decomposes water, releasing hydrogen gas, and thus only the colorless ytterbium(III) ion occurs in aqueous solution. 

Samarium and thulium also behave this way in the +2 state, but europium(II) is stable in aqueous solution.

Ytterbium metal behaves similarly to europium metal and the alkaline earth metals, dissolving in ammonia to form blue electride salts.

Free hypophosphorous acid, H3PO2, is prepared by acidifying aqueous solutions of hypophosphite ions, H2PO2-. For example, the solution remaining when phosphine is prepared from the reaction of white phosphorus and a base contains the H2PO2- ion. If barium hydroxide, Ba(OH)2, is used as the base and the solution is acidified with sulfuric acid, barium sulfate, precipitates and an aqueous solution of hypophosphorous acid results.

The pure acid cannot be isolated merely by evaporating the water, however, because of the easy oxidation of the hypophosphorous acid to phosphoric acids (and elemental phosphorus) and its disproportionation to phosphine and phosphorous acid. The pure acid can be obtained by extraction of its aqueous solution by diethyl ether. Pure hypophosphorous acid forms white crystals that melt at 26.5° C. The electronic structure of hypophosphorous acid is such that it has only one hydrogen atom bound to oxygen, and thus it is a monoprotic oxyacid. It is a weak acid and forms only one series of salts, the hypophosphites. Hydrated sodium hypophosphite, NaH2PO2×H2O, is used as an industrial reducing agent, particularly for the electroless plating of nickel onto metals and nonmetals. https://erowid.org/archive/rhodium/chemistry/hypophosphorus.html

Ketone-catalyzed decarboxylation, as described by Drone #342:
Decarboxylation is accomplished by mixing about 80 g tryptophan in 250 mL of high-boiling solvent (xylene, DMSO, cyclohexanol, etc.), adding a dash of a ketone (I like 5 g of cyclohexanone, but a couple grams of MEK works reasonably well), heat it to around 150 deg, and when evolution of CO₂ ceases/solution is clear, the reaction is complete. This takes anywhere from 1.5 to 4 hours. After this is over, the solvent is boiled off (or at least greatly reduced in volume), and the residue is dissolved in DCM. This is washed with a 5% NaHCO₃ solution, then a distilled water solution, then the DCM layer is separated off, dried with MgSO₄, and the DCM is boiled off. You now have reasonably pure tryptamine. https://erowid.org/archive/rhodium/chemistry/tryptophan.html

I ordered 100 grams of diethylamine HCl after all. I decided in the end to go with it because I really want to do some of the experiments I've read about using lanthanide diiodides in secondary amines. The papers I've found use diisopropylamine but that stuff is $40 for something like 30 mLs! I will be able to generate twice as much amine for half the price if I can make it work with diethylamine instead of diisopropylamine. Eventually I'd like to try both. But for now I will try the diethylamine and see if it works. To my knowledge no one has tried this yet (not that I can find in the literature anyways; I'm sure it's been done before).

That stone is STILL strongly colored! It's been sitting out for several days now and it is even more strongly colored now than it was to begin with! But for spilling that reaction mixture I would never have dreamed that stuff would do this to stone. You can see that even some of the crystals have taken up the color. I'm sure it's just a surface coating but I have no idea what is bonding it to the quartz. And using other amino acids doesn't work; I've already tried. Only tryptophan does this out of the ones that I've checked so far. How freaking cool is that?

As I tinker around with several different experiments trying to make them video-worthy I was thinking of simple, easy things that I could do that would still be semi-original but that people would be interested in. I found a paper where the authors did an extraction of harmala alkaloids from passion flowers that I thought would be really cool. I have some ground up Syrian Rue that I could extract it from which should give me a decent yield (I don't have enough material to do passion flower unfortunately). However, it would all be done the same and the same method could be applied to any alkaloid extraction since it's very generalized. 

I just found a 52 page thesis called "The Synthesis of Heterocycles from Anthranilic Acid and its Derivatives" on Google!! It's loaded with all kinds of goodies; tons of information on anthranilic acid and its reactions. It gives a general outline on how to do the reaction between anthranilic acid and chloroacetic acid (a very general outline) but it might just be enough to work from. The same paper also gave some great info on how to get esterification reactions to dominate over N-alkylations so that should help in my ethyl anthranilate synthesis as well. I'll tell you what these undergrad and grad level theses are really turning out to be super helpful!

Tuesday, September 17, 2019

Today I am going to do a full test of the tryptaldehyde synthesis. If it works there will be a video on it in the near future. I don't see why it wouldn't work at this point. I'd also like to try the esterification reaction with some of the anthranilic acid I made to make a small amount of ethyl anthranilate to test the reaction before I film it. Now would be a good time to have some too because the mosquitoes are a real pain in the ass in the evening around here.

I just figured out how to separate out the tryptaldehyde from the reaction mixture!!! As it turns out I don't need to use a solvent based extraction at all! The paper that I am working from references an old practical organic textbook from 1973 for their method of separating out the aldehyde and I just managed to get a copy of it (Vogel's Textbook of Practical Organic Chemistry, 3rd Edition pgs 331-332). This is so neat they use an excess of a saturated water/ethanol solution of sodium bisulfite to precipitate out the aldehyde. This is an equilibrium reaction so once filtered off the free aldehyde is easily regenerated by reaction of the solid with aqueous sodium carbonate or hydrochloric acid to remove bisulfite ion and shift the equilibrium back to the left. What a kick ass cool trick!!!

I've decided not to do the video on diethylamine after all. The reason being it's just too readily available and too cheap to really make it worthwhile. If I was to get diethylaniline and make diethylamine from that it would cost me $40 with shipping and at best I could expect to make about 20-30 mL of diethylamine. However, you can just buy diethylamine hydrochloride on eBay and 100 grams is $19.90 with free shipping. That being the case why would you need to make it out of OTC stuff? You can just buy it for cheap.

My anthranilic acid video is now my most viewed video on BitChute and it grew in views more than twice as fast on YouTube as any other video that I've put out. The first Reagent Test video is still number one in its steady growth in views and the Dilithium Telluride clusterfuck video is still my most viewed video of all time but the anthranilic acid one is the best performing one even if it hasn't racked up as many views as those others. The tryptaldehyde video should be another good one. Succinimide would also be good if I could get it to fucking work WITHOUT cracking any more round bottom flasks!

So I discovered this totally by accident. If you pour the reaction products of tryptophan, potassium ferricyanide, and potassium hydroxide (indole-3-acetaldehyde is one and potassium ferrocyanide is another) out onto stone and leave it in the shade for a while it turns the stone blue/green. It doesn't wash off with water (at least, not easily). It doesn't stain very pure quartz crystals well but it adheres to every kind of stone I've tried it on thus far. I have no idea what it is but it doesn't work with other amino acids, tryptophan and potassium ferrocyanide, indole-3-acetaldehyde dinitrophenylhydrazone, or potassium ferricyanide, Brady's Reagent and ferrocyanide mixture. Only the reaction product of that particular reaction does it. And it won't do it in the sun but once you put it in the shade (even if you've rinsed it off first) then the color changes. However, if you rinse it first then the color isn't as vivid. I found all of this out just by playing with this thing. It's pretty neat. Wish I knew what it was.

I am glad that I decided to film the anthranilic acid synthesis again. I knew that trying to do it with nothing but a Wikipedia entry and a bare bones synthesis protocol would be a challenge but I managed to screw it up somewhere along the line. But that's alright. I am pretty sure I've identified all the errors so I am going to try it again today. I think the thing to do is to control the temperature and pH more carefully and change the way things are added together. The protocol literally reads as "put everything in a beaker and dissolve it" as the first step. I thought that seemed kind of weird but I went with it anyways and that's when things started getting wonky. I am still not sure what product I actually got. It could be anthranilic acid and the yield just sucks. But during the synthesis I could smell ammonia and I REALLY shouldn't have been able to smell ammonia! The only place ammonia could have come from is the amino group on the benzene ring. How the holy hell that was removed off benzoic acid I have no idea but there you have it.

I finally broke down and watched ChemPlayer's video on doing this reaction and I confirmed a few suspicions and picked up a few tips. I hate to do that because I don't want to just repeat what someone else does. So I am going to stick with the prepchem protocol but with a few minor modifications. This should do the trick. Fingers crossed!!!

Succinimide failed. I'm beginning to think I'm losing my touch.  I am going to try doing the anthranilic acid synthesis today. Hopefully that one works better (third times the charm). I know why succinimide failed (I think). I am going to dry the ammonium succinate more thoroughly, come up with a better apparatus, and then try again later. I really hope that SOMETHING works soon!

1. 20 g of finely powdered phthalimide and 40 g of sodium hydroxide are dissolved together in 140 ml of water, the solution being cooled during the operation.
2. The solution is agitated, and 200 g of a 5% solution of sodium hypochlorite run in.
3. When all is added, the solution is warmed for a few minutes at 80° C to complete the reaction;
4. it is then cooled and neutralised exactly with hydrochloric acid (or sulphuric acid).
5. An excess of strong acetic acid is added to precipitate the anthranilic acid, which is filtered off and washed with water.
6. Any anthranilic acid remaining in the filtrate is precipitated as copper anthranilate by the addition of a saturated solution of copper(II) acetate.
7. After standing for some time the precipitate is filtered off and suspended in a small quantity of warm water, while a current of hydrogen sulfide is passed into the suspension.
8. The copper sulphide formed is filtered off, and anthranilic acid recovered from the filtrate by concentration on a water bath.
9. It may be recrystallised from hot water. Total yield 85%, m.p. 145° C.

OK the synthesis of potassium bromate/bromide is not turning out to be great video material. I think that every little thing that could go wrong did. I got a good yield of potassium bromate (21.4 grams before drying which is about what I got the last time I did this) and I might take that footage and compile a smaller video of just that later on. Looking back at the videos I've done people seemed to like the ones where I was doing something for the first time the most. So I've decided to switch gears and while I work on salvaging the potassium bromide I am going to film a synthesis I have never done before and I think it's one that people will like. I am going to do the synthesis of succinimide from succinic acid. As an added bonus I can take that succinic acid product and convert it into N-bromosuccinimide in a future video (the process look pretty simple).

1. 20 g of succinic acid are dissolved in a small quantity, of water in a basin,
2. and the solution neutralised with ammonia.
3. The solution is boiled to expel excess of ammonia,
4. after which a further 20 g of succinic acid dissolved in water are added.
5. The solution is evaporated to complete dryness on a water bath;
6. the dry residue is transferred to a retort and heated quickly with a large luminous flame.
7. The sublimate of succinimide is recrystallised from pure acetone. 
   1. Yield 70%, colourless rhombic plates; m.p. 126° C; b.p. 288° C.

The tetrahydrofuran and phthalic anhydride arrived yesterday!!! I am SO excited! I finally managed to find a source for anhydrous tetrahydrofuran. Thank the magic sky daddy that it can be recycled out of any experiment I use it in! Just 120 mL was $72!!! But it's highly pure and anhydrous so I can use it directly in the lanthanide diiodide experiments without having to dry it over anything more than a small piece of metallic sodium. I went ahead and got some phthalimide as well which is only one step away from anthranilic acid and will probably yield a purer product. However, I am still going to demonstrate the conversion of phthalic anhydride into phthalimide and having the phthalic anhydride is good because that gives me a pure product to compare to what I get when I attempt the oxidation of naphthalene. 

I finished cleaning up the sodium metal. In the end I was able to get one giant lump and a couple of smaller spheres which got lost in the goop left after cleaning the metal and so ended up in the trench in the end along with myriad tiny pieces of sodium metal. It was pretty cool since the large amount of mineral oil kept many of them from reacting with the water for quite a long time. I cleaned the metal by heating it up in mineral oil, melting it down, breaking it up into tiny spheres, changing out the mineral oil a couple times, and finally by adding small amounts of azeotropic isopropanol to the hot oil with stirring. The alcohol breaks up the crud enough to allow the beads of sodium to conglomerate into a single large piece. Then I just let it cool down, skewered it with a glass rod, and then transferred it to a jelly jar with mineral oil. Tomorrow when I have more time after work I will cut this into small pieces and then I will be ready to keep THF (and any other ethereal solvent) bone dry and peroxide free for the foreseeable future. YAY!  Now I can go buy some starter fluid and distill some diethyl ether and actually keep it around instead of having to distill it every damn time I need some!

I worked a very long day yesterday but I managed to get that block of sodium metal I've had for ages all cleaned up. I watched NileRed's video on how to do it and it turned out to be very easy. I was a little worried since the block of sodium I had was covered in this peach colored substance but when I melted it in mineral oil I found that the surface layer of crud was much thinner that I had previously thought. Another point for eBay sellers of chemicals.  I wasn't able to fully clean it last night so I will finish it tonight. An added bonus was that I was able to break up that block of sodium into many little beads which is fantastic. I only need small amounts at a time. Once this sodium metal is fully cleaned I will keep it stored under dollar store mineral oil just like the lithium and potassium already are. And once the THF arrives I can make sure that open bottles of the stuff stay anhydrous by putting a small, clean bead of sodium into the bottle. This is all working out BEAUTIFULLY!!!

I have checked every single listing that I can find and I have confirmed that indole-3-acetaldehyde (a.k.a. tryptaldehyde) is not a listed chemical or a controlled substance. Nor is tryptamine which frankly stunned me. I think that a video on making tryptamine might be going a little too far but tryptaldehyde is totally fair game and should be edgy enough to get some subs and clicks without landing me in any kind of trouble.

Tryptamine is only one small step away from becoming dimethyltryptamine and I don't want people thinking that I am encouraging (or god forbid engaging in) that kind of thing. I am less worried about the anthranilic acid because for it to be misused you would have to 1) turn it into N-acetylanthranilic acid and 2) then you would have to react it with o-toluidine in order to form methaqualone. And if you were to search my lab one thing you would notice is the distinct lack of o-toluidine or anything that could be turned into to o-toluidine without undertaking a massive multi-step synthesis. Also, not all of that phthalic anhydride will be turned into anthranilic acid. I have a few other projects in mind for the rest of it after I am done with the anthranilic acid projects (the grape flavoring that doubles as an insect repellent, indigo dye, and the TLC research).

Actually I am very curious to see how well tryptaldehyde chelates metal ions for my TLC project. Anthranilic acid forms spectacularly stable complexes with transition metal cations and I want to see how I can expand on that. In anthranilic acid the metal is chelated to the ionized carboxyl group and the amino nitrogen lone pair according to some of the literature I've seen so far. However, I would think that given the structure of tryptaldehyde that it could form a coordinate covalent bond to metal cations via the amino nitrogen lone pair and the carbonyl lone pairs. I could be totally off on that one but the best way to find out is to do the experiment and see what you get.

Reductive Amination with Sodium Triacetoxyborohydride - Modern Organic Synthesis in the Laboratory, pg 83

It was insanely expensive but I was able to find 120 mL of anhydrous THF for sale on eBay. I am going to clean that block of sodium I have so that I will have some sodium spheres to store it over when it arrives. I want that stuff to stay 100% dry. The stuff that I have is still very cloudy even after this second round over the sieves. I think that these aren't the best sieves in the world (or it's REALLY wet) but I am to the point where I am ready to try a different drying agent like magnesium sulfate. Can't find any info about attempting that very thing so will probably try it on a small scale. If it clumps then it's not just the sieves. Eventually I will be able to get it dry. I am going to have to distill it at some point and that's always fun. Distilling ethers is NOT my idea of a fun time. One must be very, very careful and there is always a loss because I don't dare distill it dry even with the BHT and sieves keeping the peroxides to a minimum. But I should be able to recover 50 mL of dry THF from that at least and then that stuff is going to be saved and cared for as if it were liquid gold. Hell I don't take that kind of care with the chloroauric acid so MORE than liquid gold! LOL!

The rain precluded doing any distillation today so I don't know if my second 2,2-dimethoxypropane experiment worked or not. Since it doesn't look like it's going to clear up anytime soon I decided to scrap it and try again the next time I have a day off. That gives me time to dry the acetone and methanol more thoroughly anyways so that might be a good thing.

I've decided to scrap trying to do a synthesis of anthranilic acid from naphthalene. It looks like phthalic anhydride from naphthalene is kind of a pain in the ass and since you can just buy phthalic anhydride cheaply and easily (100 grams for about $20 counting shipping on eBay) I am just going to start with that instead. The plan would be to convert some of the phthalic anhydride to phthalamine and then oxidize that with bromate to anthranilic acid. That is a very attractive pathway because it produces metal-free anthranilic acid that I can use to synthesize pure anthranilic acid-metal cation complexes that I can then compare with the products of the 2-nitrobenzoic acid reduction using metals in acid. I have been looking at other beta and gamma amino acids which should also form very stable metal complexes which could be used for identification of metal cations in solution by TLC on silica gel like conventional organic compounds. I need to do some research and come up with an appropriate mobile phase so that I can start monitoring the progress of these chemical reactions using TLC. I have plenty of plates. Just need a good protocol.

The other experiment I have going on that I hope will turn out to be video-worthy is the tryptaldehyde synthesis from tryptophan. I found a VERY interesting paper discussing the reaction kinetics of tryptophan oxidation using hexacyanoferrate(III) and catalyzing the reaction with Cu2+ ions. It looked very promising but while detecting the aldehyde and proving the reaction worked will be childs play (use of Brady's Reagent will produce a dinitrophenylhydrazone whose mp can be easily measured) I don't know how practical it is going to be trying to extract and purify the aldehyde from the reaction solution. Hopefully simple extraction with an organic solvent followed by evaporation under vacuum is all that will be required.

Videos that are DEFINITELY coming in the near-ish future are:
1) synthesis and isolation of acetone oxime using hydroxylamine
2) synthesis of isopropylamine by reduction of acetone oxime using sodium borohydride in refluxing methanol
3) synthesis and crystallization of sodium nitroprusside
4) synthesis and isolation of sodium hexanitritocobaltate(III)
5) Cleaning metallic sodium

Videos for the the coming months are:
1) attempt at diiodomethane (DIM) from dichloromethane by Finkelstein Reaction (general method for producing alkyl iodides)
2) synthesis of 1,2-diiodoethane (DIE) from ethylene glycol using phosphorus triiodide
3) Kagans Reagent by direct reaction of samarium metal powder with DIM and/or DIE in dry THF
4) Reduction of an organic compound using Kagans Reagent
5) Diethylamine from DEET
6) synthesis of an anthranilate based insect repellent / artificial flavoring (it's both!)
7) synthesis of disulfur dichloride
8) synthesis of thionyl chloride (and possibly phosphoryl chloride)
9) synthesis of indigo dye from anthranilic acid and chloroacetic acid

"Alternatively, the methanol can be dried from magnesium methoxide. Magnesium turnings (5 g) and iodine (0.5 g) are refluxed in a small (50-100 mL) quantity of dry methanol (from a previous batch) until all of the magnesium has reacted. The mixture is diluted (up to 1 L) with reagent grade methanol, refluxed for 2-3 hours then distilled under nitrogen." https://chem.libretexts.org/Ancillary_Materials/Demos%2C_Techniques%2C_and_Experiments/General_Lab_Techniques/Drying_Solvents

"Several years after Kagan’s seminal work, Imamoto described a more atom economical method for the synthesis of SmI2 using samarium metal and iodine as the oxidant in refluxing THF [at 65 C]. " Preparation of Samarium(II) Iodide: Quantitative Evaluation of the Effect of Water, Oxygen, and Peroxide Content, Preparative Methods, and the Activation of Samarium Metal, Michal Szostak, Malcolm Spain, and David J. Procter, Journal of Organic Chemistry (2012) 😳😍🥰 If I didn't need to use up any of my phosphorus producing 1,2-diiodoethane that would free up more for doing other cool experiments. It would also make producing this reagent FAR easier for the everyday person who might wish to make use of it. Think of it: a very powerful and versatile reducing agent able to compete with most hydride reducing agents made using nothing more than samarium metal powder, iodine, and anhydrous tetrahydrofuran. The THF is actually the harder one to find. The Chinese will happily sell you all the samarium metal powder and iodine you want for very reasonable prices. And while iodine is regulated and you shouldn't buy more than a couple hundred grams a year at most it is happily highly recyclable.

After successfully producing an anthranilic acid-tin(II) complex I decided to look for a more effective way to produce anthranilic acid than by the use of 2-nitrobenzoic acid. Unless a synthesis pathway presents itself that does not use metals that idea is pretty much done for now although I will continue to run the odd experiment to see if I can eventually crack this problem just for fun. I think instead that I am going to buy 100 grams of phthalic anhydride, convert that into phthalamine and then open that ring up to produce anthranilic acid that way. What's also great about this is that I can open some phthalic anhydride up to produce phthalic acid and then compare that with the product that I get from the naphthalene oxidation with cold, alkaline KMnO₄. I can't do that until payday though so until then I am going to continue working on the 2,2-dimethoxypropane synthesis. 

Melting point of Lithium = 180.52 ^oC, Sodium = 97.79 ^oC, Potassium = 63.5 ^oC, Rubidium = 39.3 ^oC, Cesium = 28.44 ^oC. I got the alkali metals out to play with finally. I think that I will do a video on cleaning up my sodium metal tomorrow. Perhaps I will see if I can melt that lithium into a single chunk as well. That could be pretty cool. Then I can use that sodium metal to keep the THF dry and I can use it to FINALLY keep some diethyl ether! Not only will it keep it 100% dry it will also keep peroxides from forming. That's a pretty nice two-fur if I do say so myself. :-) 

Friday, August 23, 2019

OK so I think I've got a much more efficient way of synthesizing isopropylamine. The plan now is to react acetone with hydroxyamine to form acetone oxime. This can then be reduced to isopropylaime by refluxing the oxime with sodium borohydride in methanol. That should do the trick. I have a protocol from PrepChem on synthesizing and isolating acetone oxime. Doing the reduction will be simplicity itself. And this may lead to a general way to produce primary and secondary amines that is much better than the ways I have previously considered.

I didn't get a chance to try the DEET experiment yesterday. I spent most of the day making bromine and fresh anhydrous magnesium sulfate as well as drying the living hell out of my molecular sieves. I wish I could come across a good method for synthesizing THF or find a good supplier for it. It's so damn hard to come by and I really need it for these lanthanide diiodide experiments. THF stabilizes the divalent lanthanide complex. However, it looks like isopropylamine will also work for that. Isn't it nice when things just kind of segway together into one overarching project? Makes things so much more convenient.

The more I look at it the more I think that I have cracked the TLC enigma. Complexing the cations with beta and gamma amino acids will result in pentagonal and hexagonal complexes between the metal cations and two amino acid substituents. With a beta amino acid like anthranilic acid these complexes are high stable and (I think) soluble in organic solvents. Since the organometallic complex should behave more or less like an organic chemical species it should be separable using conventional silica gel TLC. Detection would probably be via fluorescence although if an amino acid can be found that will complex with metal cations and then undergo another reaction where it acquires a strong color then that could make the task even easier. I may have to synthesize some designer beta and gamma amino acids in order to investigate this properly but I am pretty damn sure this will work.

A thesis on the reduction of 2-nitrobenzoic acid to anthranilic acid. That paper also gives the synthesis of indigo blue from anthranilic acid. So I can make a new, cutting edge insect repellent AND indigo dye. OK I know what project I am working on now. I have just enough 2-nitrobenzoic acid to do both experiments. Since 2-nitrobenzoic acid is kind of a hard chemical to come across (unless you're ready to either make it or spend beaucoup bucks buying it) I want to make sure I get it right since I won't be able to replace it. That doesn't give me a lot to work with so far as getting all the bugs out of the reactions before filming them. But I think that it is do-able. https://archive.org/details/reductionofortho00pfaf/page/n15

As far as the DEET to DEA (diethylamine) project is concerned it is now just a matter of doing a run that actually works. If we can recover any DEA at all this time around I will be satisfied. We are having a heat wave today so I need to wait until my roomie comes home in a few hours with some ice before doing the experiment. But so long as we don't get any pop-up storms I will be able to give it another go this afternoon while I am working out the kinks to the 2-nitrobenzoic acid reduction. I was also thinking of playing with some metal chem today (because I feel like I've wasted the day if I don't) so maybe a nice anhydrous thulium salt or something could be cool. 

2-Nitrobenzoic Acid: off white powder, CAS Number = 552-16-9, molar mass = 167.12 grams/mole, melting point = 147.5 ^oC, boiling point = 340.7 °C at 760 mmHg, pKa = 2.47. Soluble in ethanol, ethyl ether, acetone, methanol, somewhat soluble in water (7.85 grams/liter), and chloroform, very slightly soluble in benzene and carbon disulfide. If heated to decomposition it emits very toxic fumes. 

Anthranilic Acid: odorless white or yellow solid, CAS Number = 118-92-3, molar mass = 137.138 grams/mole, melting point = 146 - 148 ^oC, boiling point = 200 ^oC (sublimes), pKa = 2.17 (carboxyl) and 4.85 (amino). Very soluble in chloroform, pyridine, soluble in ethanol, diethyl ether, slightly soluble in trifluoroacetic acid, benzene.

As it turns out samarium dihaldes are extremely sensitive to exposure to air. I realized this after attempting to repeat the previously wildly successful synthesis of samarium(II) bromide. I tried making the diiodide and dibromide of samarium and while I had some success with the dibromide (it began to break down rapidly on being exposed to air even while still in a red hot crucible) but with the diiodide I got absolutely nothing so far as I can tell. Only this slightly off-whitish yellow compound that does not dissolve readily in water. BTFOM what is is. (8/11/19: samarium oxyiodide or samarium oxide most likely) I desperately need to find descriptions of the samarium oxyhalides and their properties in the literature.

"Tennessee Eastman Acetic Anhydride Process
Acetic anhydride is produced by carbonylation of methyl acetate (methyl ethanoate) in a process that is similar to the Monsanto acetic acid synthesis. Methyl acetate is used in place of methanol as a source of methyl iodide. In this process lithium iodide converts methyl acetate to lithium acetate and methyl iodide, which in turn affords, through carbonylation, acetyl iodide. Acetyl iodide reacts with acetate salts or acetic acid to give the anhydride. Rhodium iodides and lithium salts are employed as catalysts. Because acetic anhydride hydrolyzes, the conversion is conducted under anhydrous conditions in contrast to the Monsanto acetic acid synthesis.

"Tryptaphan is oxidized by sodium hypochlorite, resulting in the aldehyde (this special reaction of alpha amino acids was well studied in the '30s, one ref here: http://chemistry.mdma.ch/hiveboard/rhodium/pdf/tryptophan.st... )" - http://www.sciencemadness.org/talk/viewthread.php?tid=39224

"Reaction between NaOH and DEET in a solution of water and ethanol (say, 50/50 mixture) should proceed relatively easily at room temperature. I'd recommend magnetic stirring if possible, and having a heating option available in case the reaction decides to proceed slowly. A sign that the reaction is proceeding would be heat. I doubt the reaction would take more than an hour or so once started. Distillation should be simple enough. Diethylamine boils at 56C, ethanol at 78C, water at 100C, and DEET at 111C. Separation of fractions shouldn't require any special distillation equipment unless your heating mantle unfortunately happens to be a brick of thermite. And yes, I would recommend collecting only the fraction that comes over at around 56C." - http://www.sciencemadness.org/talk/viewthread.php?tid=954

OTC Hydrolysis of N,N-diethyl-meta-toluamide (DEET) to Diethylamine and M-toluic acid

"To a 250ml autoclavable media bottle is added in order, 175ml N,N-diethyl-meta-toluamide (98.11% comerc grade, $15) followed by 40ml 70% EtOH. the media bottle is capped and vigorously shaken for one minute. the EtOH and DEET should now be a homogenous mixture. to this solution is added 40g NaOH and once again capped. the media bottle containing the mix is now sealed and heated in a hot water bath (crock pot set on low) added to the bath at 55*C (125*F) ending at 70*C (160*F) periodically agitating for the length of time it takes to completely dissolve the NaOH plus 1.5hr. the solution should now be a deep yellow color the crock pot is turned off and allowed to cool to RT. it is removed from the bath and allowed to stand at RT for one day minimum. the bottle will then be carefully opened after cooling in the refrigerator for 1hr. observed was the strong smell of diethylamine, no longer did it smell of DEET and EtOH. the solution is fractionally distilled (don't forget boiling chips, this stuff likes to bump) collecting the fraction along a 9 degree temperature arc centered on 55*C (51-59*C). the solution may solidify towards the end of the distillation and a small amount of DH2O can be added to liquify the waxy mass of M-toluic acid and NaOH. total yield form approximately 225 ml of solution was 57ml of crystal clear diethylamine in freebase form. 25.3%.
MeOH can be used in a pinch but i like EtOH, it mixes better with the DEET and has just enough water for the hydrolysis but not enough to cause separation. Diethylamine C4H11N 73.14g/mol boiling point 55.5*C (131.9*F).

I keep putting off the GeI₄ experiment because I keep thinking of things that need to be checked. However, no matter how I look at it I can't see a reason why it wouldn't work. My idea is to create germanium tetraiodide in exactly the same way I would create tin tetraiodide except for the GeI₄ dichloromethane is replaced with chloroform. I₂ will still dissolve readily in chloroform and if germanium metal is refluxed in that solution it should theoretically produce GeI₄ which is also soluble in chloroform. That will remove any passivating crust of GeI₄ from the metal as it forms which should keep the reaction going. Again, almost exactly the way tin tetraiodide is made. It should work. I think. DCM might also work for GeI₄. Not sure because the lit doesn't say anything about that one way or the other. It just references chloroform and a few other non-polar solvents that I don't have.

I had no idea that trichloroacetonitrile could be of such utility in organic synthesis! I only looked it up because I was thinking about chloral earlier and was curious about other chlorinated analogs of common compounds. This is one of those things where I would never have looked at this but for idle curiosity and my curiosity was rewarded beyond anything I could have imagined. "...the chlorination of acetonitrile saturated with hydrogen chloride leads to pure trichloroacetonitrile even at 50-80 °C in good yields. Due to the high reactivity of the chlorine atoms, trichloroacetonitrile can be used (especially in combination with triphenylphosphine) to convert allylic alcohols into the corresponding allylic chlorides. With carboxylic acids, acyl chlorides are obtained." Could this be a viable general synthetic pathway to acyl chlorides? The mind boggles at the possibilities! And that's not all trichloroacetonitrile is good for! Check out the Wikipedia article for a larger listing: https://en.wikipedia.org/wiki/Trichloroacetonitrile#Use

Cl₂ + I₂ --> 2ICl
2ICl + 2H₂O --> 2HCl + 2HI + O₂

The HCl and HI can be separated by fractional distillation. Azeotropic HCl boils at 110 ^oC while azeotropic HI boils at 127 ^oC. This should be a viable pathway to generate hydriodic acid from elemental iodine.

The more research I do the more the "Breeder Reactor in a Bottle" experiment looks feasible. There is one minor problem in that Radium²²⁶ may not be radioactive enough for measurable results to be obtained. The more I look at it the more I think that Americium²⁴¹ AND Radium²²⁶ would be the way to go. Both emit alpha particles with energies in the 4+ MeV range with Americium²⁴¹ emitting an alpha particle with 5.48 MeV of energy. This is in the same neighborhood as alpha particles given off by Plutonium²³⁸ and Polonium²¹⁰ which are the usual alpha sources used to induce Beryllium⁹ neutron emission. It should be more than adequate to react with Beryllium⁹ to produce excited Carbon¹³ which will then decay to ground state Carbon¹² with emission of a fast neutron. This can be moderated by heavy water or plain old graphite powder to produce thermal neutrons which should be able to bind to Thorium²³² or Uranium²³⁸ to produce Uranium²³³ or Plutonium²³⁹, respectively.

Unfortunately I don't have a gamma ray spectrometer so I wouldn't be able to detect those isotopes directly but since U²³³ and Pu²³⁹ have much shorter half lives than Th²³² or U²³⁸ a general increase in radioactivity should signal a successful experiment. The actual reactor bottle would have to be very small, perhaps 10-20 mL in volume at the most (20 is probably way too big for the very tiny amounts of reactants I would be using). As far as shielding from the neutron radiation (the biggest concern by far) I have already come up with a way to totally mitigate that. Store the reaction bottle inside another bottle full of a concentrated solution of a soluble boron compound and a soluble cadmium compound. Boron and cadmium are efficient neutron absorbers as is the water they would be dissolved in. In the event of an accident the reaction bottle can simply be broken inside the shielding bottle. The solution in reaction bottle would mix with the solution in the shielding bottle which would both dilute it to harmlessness AND shut down all nuclear reactions pretty much completely. So it should be extremely safe. I suppose that lead shielding could be used around the shielding bottle but it won't be necessary. Lead is not always the wisest way to go anyways. Bremsstrahlung is a thing.

Another issue is that I have not been able to confirm whether this is strictly legal or not. Everyone just assumes it would be a problem. But these are the same people who assume you can't buy thorium, uranium, radium or americium without 40 different permits which is just plain false so their opinions don't carry a lot of weight. 12 year olds can build fusion reactors in their garage and people call them brilliant. Why can't I put together 5 mL of a breeder reactor solution? A breeding reactor solution has never been done to my knowledge. It absolutely should work. It probably just isn't the most efficient way to go about producing fissionable material which is why it's not used by the military or the nuclear industry.

If natural uranium were used instead of depleted uranium then it is conceivable that some of the neutrons would be consumed causing U²³⁵ to fission. This is undesirable as without a gamma ray spectrometer there is no way to distinguish between an increase in radioactivity caused by fission of U²³⁵ (and its decay products) and that caused by decay of freshly minted U²³³/Pu²³⁹. While the amount of U²³⁵ is very small (~0.7%) I don't know if it would be detectable or not. Probably would be best to use depleted uranium in the experiment just to be sure.

What would happen if you created a solution of radium 222, americium 241, beryllium 9, and thorium 232 (or uranium 238) salts in heavy water? Would you have created a mini breeder reactor in a scintillation vial if everything was concentrated enough? It would be easy to detect. All you would have to do is create the solution and then watch for an increase in radioactivity. You would need the radium and americium because they give off alpha particles with enough energy to induce the beryllium to emit neutrons which would then be moderated by the heavy water and would bind to some of the thorium or uranium atoms creating uranium 233 or plutonium 239, respectively. I wonder if it would work better in light water with graphite particles suspended in the solution by stirring, increased viscosity from a high concentration of the salts, or both? A nuclear reactor in a bottle... :-D

The new reagent library is proving to be very useful. Already I've been able to use it to figure out exactly what the tantalate solution that I made yesterday is doing. Well, not exactly but close. It definitely contains dissolved potassium tantalate since it makes a light ppt with magnesium sulfate and strontium chloride and a very voluminous ppt with barium acetate. However it did not throw down a ppt with silver nitrate which it should have done. I am not sure if the pH is the problem. I have yet to acidify it or boil it. But I am about to play with this some more. We have a storm about to come through but that shouldn't stop me from filming a synthesis of tantalum pentoxide from the metal. I thought about putting niobium in this one too since it's chemistry is VERY similar to tantalum but I might have a different use for the niobium I have so I am going to hold off on that for now. The next elements I will tackle after tantalum will be zirconium and hafnium and then I will probably do some stuff with antimony. My experiments with samarium continue. Samarium(III) iodide hexahydrate has definitely been produced and it's as free of the oxyiodide as I can possibly make it. The next step with that would be to grind it up with 10x it's mass of ammonium iodide and then heat it up. I wonder if I can do that in some kind of apparatus because I am going to lose a TON of iodine during that process and I try to recycle every bit of precious iodine that I can. If I could capture the vapor that would be really helpful.

Antimony trioxide can be produced by fusing antimony with potassium nitrate and potassium bisulfate. Dissolving in concentrated nitric acid produces a mixture of oxides. Antimony pentoxide can be reduced to the trioxide by treatment with sulfur dioxide or hydriodic acid. Sulfur dioxide can also be formed by the action of dilute sulfuric acid on sodium sulfite or bisulfite. 

Dissolve tantalum by fusion with potassium hydroxide. Boil this tantalate with a dilute acid to produce tantalum pentoxide gel. 

"Hydrated tantalum pentoxide is a white, amorphous substance. A crystalline form is stated to be obtained when tantalum pentachloride is treated rapidly with water; the precipitate thrown down is dried slowly and again treated with water. A granular variety is produced when sodium tantalate solution is treated with sulphur dioxide and the flaky precipitate is dried. Tantalum pentoxide gel becomes incandescent and loses its water content when it is rapidly heated to 500° C., unless it has been previously aged by washing with water. This "glow " phenomenon is also displayed by hydrated chromium sesquioxide, by aluminium oxide, and by titanium dioxide. " www.atomistry.com

Niobium can be dissolved in hydrofluoric acid. Tantalum burns when gently heated with chlorine. It reacts slowly with sulfur and selenium. It is slowly dissolved in boiling concentrated sulfuric acid. It is soluble in hydrofluoric acid. Fusion of niobium or tantalum with caustic potash in air yields niobates or tantalates, respectively. 

Iridium can be dissolved by using the same KOH and KNO₃ mixture that I used to dissolve the ruthenium yesterday! I am so excited that I finally found a straightforward way to change metallic iridium into something chemically interesting! The reaction produces iridates (potassium iridate?)

Iridium can be converted to potassium chloroiridate by the action of chlorine on a hot mixture of iridium powder and potassium chloride. Precursor to thallium chloriridate (thallium nitrate and potassium chloriridate). Dissolving iridium black in hydrochloric acid produced iridium tetrachloride while any trichloride produced is converted to the tetrachloride with aqua regia. Lithium iridate possible synthesis: fusion of lithium and iridium powder in air?

Iridium can be converted to iridium disulfide by the action of an alkali polysulfide finely divided iridium. This can then be decomposed by fuming nitric acid or aqua regia (however what it decomposes into is not stated).  http://iridium.atomistry.com/iridium_disulphide.html

I have become quite caught up in my latest idea of rendering as many elements as possible into solutions for easy use in future reactions and analyses. It makes sense to do it for as many elements as possible and to make these solutions out of simple compounds likely to be encountered or useful in future synthetic and analytical work. Chloroplatinic acid, perrhenic acid, and palladous chloride were just the beginning. I found out that ruthenium can be dissolved in a molten mixture of KOH and KNO3 and the resulting green solid dissolved in water to produce an orange solution of potassium ruthenate. It may also be possible to dissolve it in a mixture of hydrochloric acid and potassium chlorate (so hydrochloric and chloric acids) to produce perruthenate. That sounds dangerous. I cannot figure out if this powdered iridium I have will dissolve in aqua regia or not. Given what I have read I don't think that it will. However, I did find that iridium will react with sulfur at atmospheric pressure to form iridium disulfide and it may be possible to enter into iridium chemistry that way. I also found that iridium will dissolve in molten sodium cyanide and this may be the better method for rendering the iridium powder chemically reactive.

Another day of rain. Yay. Rain dramatically limits what I am able to do; one of the prices one pays when one invests in things other than a fume hood. I still think that handling the various gasses/fuming liquids would be more trouble than it's worth. You would have to pipe it a fair distance away from the dogs and that would involve tens of feet of hosing that would amount to a LOT of surface area for volatile chemicals to condense on not the least of which is water vapor. While it would be possible to engineer the thing so it could drain that raises the question of how to handle the drainage from it. Moving the dangerous waste around is, funnily enough, a lot more damaging than just letting it dissipate into the environment as its generated. I've noted no ill effects whatsoever to the environment from my experiments as I have been conducting them. The only thing would be ozone damage from evaporation of the chlorinated solvents like dichloromethane which is unavoidable but which is kept to a minimum already for economic reasons. It's a bit of enlightened self-interest really. And if a fume hood isn't practical during the monsoon season that is winter around here then it sure as hell isn't practical in summer during which I have seen it go without raining at my house for more than 60 days at a time.

Although everything is barely functional I've decided to go ahead and start recording my chemical adventures on my little blog here. I am thrilled to have my own personal website again after so many years of not having one. Long ago my ex-husband set up a server in our basement and I created my first website on there. At that time the sole purpose of my website was to make my school notes accessible to myself anywhere at anytime without having to carry around a backpack full of notebooks. It worked very well and after I lost a place to host the site during my divorce I decided that when the time was right I would create an even better website than my old one and pay for everything myself. Since the "poor" in Poor Mans Chemist isn't just a metaphor it took a few years before I was in a position where I could spend money on non-essential extras like this. But now that I have it I am going to use it as much as possible. My goal is to create a website that not only fulfills the function of making my notes available to me anywhere I have internet access but that also can act as a starting point for aspiring home chemists who are looking for reliable information on how to set up their own labs and properly use them.
