Aniline

Aniline is predominantly used as a chemical intermediate for dyes, drugs, explosives, plastics, and photographic and rubber chemicals. Many chemicals can be made from Aniline, including:Isocyanaates for the urethane industryAntioxidants, activators, accelerators, and other chemicals for the rubber industryIndigo, acetoacetanilide, and other dyes and pigments for a variety of applicationsDiphenylamine for the rubber, petroleum, plastics, agricultural, explosives, and chemical industriesVarious fungacides and herbicides for the agricultural industryPharmaceutical, organic chemical, and other products
Aniline,C6H5NH2, is slightly soluble in water,miscible in alcohol and ether,and turns yellow to brown in air. Aniline may be made(1) by the reduction, with iron or tin in HCI, of nitrobenzene, and(2) by the amination of chlorobenzene by heating with ammonia to a high temperature corresponding to a pressure of over 200 atmospheres in the presence of a catalyst(a mixture of cuprous chlorideandoxide).Aniline is the end point of reduction of most mononitrogen substituted benzene nuclei,as nitro benzene beta-phenyl hydroxylamine, azoxybenzene, azobenzene, hydrazobenzene. Aniline is detected by the violet coloration produced by a small amountof sodium hypochlorite. Aniline is used as a solvent, in the preparation of compound in the manufacture of dyes and their intermediates, and in the manufacture of medicinal chemicals.
