Description

 

Aniline is an organic compound. Aniline was first isolated by destructive distillation of indigo by Otto Unverdorben. Aniline is the prototypical aromatic amine. Its main use is in the manufacture of precursors to polyurethane. Aniline is mainly produced in industry in two steps from benzene. First, benzene is nitrated using a concentrated mixture of nitric acid and sulfuric acid at 50 to 60 °C, which gives nitrobenzene. In the second step, the nitrobenzene is hydrogenated, typically at 200–300 °C in presence of various metal catalysts. Aniline reacts with carboxylic acids or more readily with acyl chlorides such as acetyl chloride to give amides. Aniline and its ring-substituted derivatives react with nitrous acid to form diazonium salts. It reacts with nitrobenzene to produce phenazine in the Wohl-Aue reaction.
