Uses- m-Aminophenol (MAP) is an important starting material for dyes, including a variety of leuco (or latent) dyes used in imaging technology, optical bleaches and fluorescent agents, drugs, agricultural chemicals; and high-performance polymers. Although the synthesis of m-aminophenol(s) by the reaction of resorcinol with ammonia or (di) alkylarnines has been known for about 100 years, the preferred manufacturing process had been for many years a route involving the sulfonation of nitrobenzene to m-nitrobenzenesulfonic acid, the reduction of the nitro group to give m-aminobenzenesulfonic acid, followed by the caustic fusion of sodium m-aminobenzenesulfonate to yield sodium m-aminophenolate. The m-aminophenol was isolated/purified by neutralization, filtration, and recrystallization; the overall yield of m-aminophenol from nitrobenzene was estimated by SRI International to be 58%.
