Description

APPLICATIONS One of the most important aromatic amines is aniline; pale brown liquid boiling at **4 C, melting at *6 C. Aniline is obtained commercially from chlorobenzene by heating with ammonia in the presence of copper catalyst or from a product of coal tar (nitrobenzene) through the reduction reaction. Aniline is the starting material in the dye manufacturing industry and as in the manufacture of others. Aniline is converted into sulfanilic acid which is the parent compound of the sulfa drugs. Aniline is also important in the manufacture of rubber-processing chemicals, antioxidants and varnishes. N-Methylaniline, a sec-amine in aniline class, is used as a latent and coupling solvent. Its important use is as an intermediate for dyes, agrochemicals and other organic products manufacturing.
