Barium acetate cyanide

Hydroxylamine-O-sulfonic acid reacts with hydrazine to form a precipitate of triazanium hydrogensulfate (H2NNH2 NH2)+ HS04. Reaction of this solution with an appropriate barium salt in 0.1 M aqueous solution yielded solutions of the nitrate, perchlorate, chlorate, acetate, cyanide, bromide, and hydroxide salts. The stability of the salts decreases in the order hydrogen sulfate > nitrate > perchlorate > chlorate > acetate > azide > cyanide > bromide > hydroxide. The stabihty of the solutions decreases with decreasing H+ concentration, thus stronger acids form more stable salts.

Synthetic chemical approaches to the preparation of carbon-14 labeled materials iavolve a number of basic building blocks prepared from barium [ CJ-carbonate (2). These are carbon [ C]-dioxide [ CJ-acetjlene [U— C]-ben2ene, where U = uniformly labeled [1- and 2- C]-sodium acetate, [ C]-methyl iodide, [ C]-methanol, sodium [ C]-cyanide, and [ CJ-urea. Many compHcated radiotracers are synthesized from these materials. Some examples are [l- C]-8,ll,14-eicosatrienoic acid [3435-80-1] inoxn. [ CJ-carbon dioxide, [ting-U— C]-phenyhsothiocyanate [77590-93-3] ftom [ " CJ-acetjlene, [7- " C]-norepinephrine [18155-53-8] from [l- " C]-acetic acid, [4- " C]-cholesterol [1976-77-8] from [ " CJ-methyl iodide, [l- " C]-glucose [4005-41-8] from sodium [ " C]-cyanide, and [2- " C]-uracil [626-07-3] [27017-27-2] from [ " C]-urea. All syntheses of the basic radioactive building blocks have been described (4). 

When a solution of barium platinocyanide is allowed to crystallise after adding a trace of barium cyanide or barium hydroxide to it, crystals of the green 8-salt axe obtained. If, on the other hand, a trace of hydrogen cyanide, hydrogen chloride, tartaric or acetic acid, or cyanoplatinous acid is present instead, crystals of the yellow a-salt are deposited. 

Indirect determinations of several types can be carried out. Sulfate has been determined by adding an excess of standard barium(II) solution and back-titrating the excess. By titrating the cations in moderately soluble precipitates, other ions can be determined indirectly. Thus sodium has been determined by titration of zinc in sodium zinc uranyl acetate, and phosphate by determination of magnesium in magnesium ammonium phosphate. Quantitative formation of tetracyano nickel-ate(II) has been used for the indirect determination of cyanide. ...

Synthetic chemical methods for the preparation of carbon-14-labeled chemicals utilize a number of basic building components that are prepared from barium carbonate ( " C). These are versions of carbon dioxide, acetylene, benzene, sodium acetate (1- and 2- " C), methyl iodide, methanol, sodium cyanide, and urea. Many complicated labeled compounds may be synthesized from these materials.
