Iodine, iodoform

Triiodoacetic acid [594-68-3] (I CCOOH), mol wt 437.74, C2HO2I3, mp 150°C (decomposition), is soluble in water, ethyl alcohol, and ethyl ether. It has been prepared by heating iodic acid and malonic acid in boiling water (63). Solutions of triiodoacetic acid are unstable as evidenced by the formation of iodine. Triiodoacetic acid decomposes when heated above room temperature to give iodine, iodoform, and carbon dioxide. The sodium and lead salts have been prepared.

Ethyl alcohol is best identified by means of its boiling point and that of the bromide, iodide,-or benzoate (463) prepared from it. Aconvenie nt test for alcohol which is often used, is made by adding to a warm aqueous solution of the substance a solution of sodium carbonate and iodine iodoform, CHI3, precipitates as a yellow powder and can be recognized by its characteristic odor. The reactions involved will be described later (266). The formation of iodoform is not a positive proof of the presence of ethyl alcohol as other substances are converted into iodoform under the conditions used in the test. ...
