Not illustrated. 1849 Excerpt: ... 10000 Hydriodate of cyaniline.--This salt closely resembles the two former, but is soon decomposed by the action of the atmosphere, iodine being separated. Of the compounds of cyaniline with the so-called oxygen acids, I have obtained only the nitrate in a fit state for analysis; this salt is difficultly soluble. Both the sulphate and oxalate are extremely soluble. Their solutions, when evaporated, are decomposed like the hydrochlorate. Nitrate of cyaniline.--The base is easily soluble in boiling, dilute, nitric acid; on cooling, a beautiful nitrate crystallizes in long white needles, which may be recrystallized, from boiling water, without decomposition. This salt is only slightly soluble in cold water, and even less so in alcohol and ether. It contains equal equivalents of cyaniline and of the hydride of nitric acid. When burnt with oxide of copper, the following results were obtained: Carbon 46-27 46 48 Hydrogen.... 4-80 4-47 leading to the formula: Cy, C12 H7 N, H N06. as the following comparison with the theoretical numbers will show: 14 equivs. of Carbon.. 8 Hydrogen 3 Nitrogen.. 6 - - Oxygen.. 1 equiv. of Nitrate of Cyani-line Nitrate of cyaniline forms a fine double salt with nitrate of silver. Platinum compound of cyaniline.--A dilute solution of the hydrochlorate of cyaniline gives no precipitate with bichloride of platinum. On mixing, however, a boiling solution of the base in strong hydrochloric acid with a concentrated solution of bichloride of platinum, the double salt crystallizes on cooling, in beautiful orange-yellow needles, which become pure when washed with ether. In the following determinations, different preparations of the salt were employed: I. 0-3488 grm. of the platinum-salt, burnt with ch...
