Aniliini riskianalüüs (eng)
In reactions localized at nitrogen or more
commonly results in the formation of new C-N bonds. In alkaline solution, azobenzene
results, whereas arsenic acid produces the violet-coloring matter violaniline. Chromic acid
converts it into quinone, whereas chlorates, in the presence of certain metallic salts
(especially of vanadium), give aniline black. Hydrochloric acid and potassium chlorate give
chloranil. Potassium permanganate in neutral solution oxidizes it to nitrobenzene, in alkaline
solution to azobenzene, ammonia and oxalic acid, in acid solution to aniline black.
Hypochlorous acid gives 4-aminophenol and para-amino diphenylamine. Oxidation with
persulfate affords a variety of polyanilines compounds. These polymers exhibit rich redox
and acid-base properties.
