3‑Aminofenol

3‑Aminofenol es un sólido cristalino blanco a rosa pálido con un olor característico tenue; tiene un punto de fusión de aproximadamente 122–124 °C y es moderadamente soluble en agua y en disolventes orgánicos. Es un compuesto orgánico aromático clasificado como un fenol sustituido y una amina aromática primaria. Principalmente utilizado como intermedio químico, sirve en la síntesis de colorantes (especialmente colorantes azoicos y sulfurados), productos farmacéuticos (por ejemplo, analgésicos y antipiréticos) y reveladores fotográficos. Sus aplicaciones están concentradas en los sectores de colorantes y pigmentos, productos farmacéuticos y productos químicos para imágenes.

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%. (Doubtless, process improvements were made by the producers using this process.) The nitrobenzene/sulfonationlreductionlcaustic fusion route is still being used commercially, notably by ACNA in Italy, the largest producer of MAP, as well as a few smaller manufacturers. Sumitomo Chemical Co. used this process as well into the early 1980s and had licensed their knowhow to Hindustani Organic Chemicals, Ltd. of India which started up a plant on this basis with a capacity for MAP of 1.5 mill. lb /yr in 1970.The output of the Indian plant was said to be devoted to making sodium p-aminosalycilate (PAS), a tuberculostatic agent.
