aniline (C6H5NH2)


aniline molecule
Also known as phenylamine or aminobenzene, a colorless, oily, highly toxic liquid that is made by the reduction of nitrobenzene. Structurally, aniline consists of a planer benzene ring, with one amino group giving the molecule basic properties; it is a primary aromatic amine.

Aniline is made by the reduction of nitrobenzene or by reaction of chlorobenzene with ammonia.

Aniline is an important starting point for making organic compounds, including some drugs, synthetic dyes, resins, and explosives. It is used in the manufacture of rubber tires, where it acts as an accelerator in the process of vulcanization by catalyzing the chemical reactions involved – shortening the heating time needed. It was also used as a propellant for some early rockets, such as the American Corporal. However, because of its toxicity, it is no longer used as a rocket fuel.
