2-Amino-4-chlorophenol-6-sulfonic acid Chemical Properties,Usage,Production

Uses

The acid is an important intermediate for dyes. It is used mainly in the manufacture of Diamond Black P 2 B and of acid chrome blue dyes.

Production Methods

2-Amino-4-chlorophenol-6-sulfonic acid obtained from p-chlorophenol by sulfonation and nitration is reduced with iron and hydrochloric acid without being precipitated. After filtering from the iron sludge, the highly alkaline reduction liquor is concentrated by evaporation and decolorized with activated carbon. Upon acidification 3-amino-5-chloro-2-hydroxybenzenesulfonic acid precipitates. Yield 72 %, based on p-chlorophenol.

General Description

Off-white solid.

Air & Water Reactions

May be sensitive to prolonged exposure to air and/or light. Insoluble in water.

Reactivity Profile

2-Amino-4-chlorophenol-6-sulfonic acid may react with strong oxidizing or reducing agents and with mineral acids and bases

Fire Hazard

Flash point data are not available for 2-Amino-4-chlorophenol-6-sulfonic acid, but 2-Amino-4-chlorophenol-6-sulfonic acid is probably combustible.
