Description and Uses
First produced in 1826 by Otto Unverdorben through destructive distillation of indigo, the first industrial use was as a purple dye, Mauveine, formulated by William Henry Perkin accidentally in an attempt to isolate quinone. The name aniline was given in deference to the indigoyielding plant, Indigofera suffruticosa, commonly named anil.
Aniline is used in the manufacture of dyes,pharmaceuticals, varnishes, resins, photo graphic chemicals, perfumes, shoe blacks,herbicides, and fungicides. It is also usedin vulcanizing rubber and as a solvent. Itoccurs in coal tar and is produced from thedry distillation of indigo. It is also producedfrom the biodegradation of many pesticides.Aniline is a metabolite of many toxic com pounds, such as nitrobenzene, phenacetin,and phenylhydroxylamine.
