Abstract

An aminophenol is made by reacting a nitro-substituted phenol with hydrogen in an aqueous alkaline medium and in the presence of a hydrogenation catalyst comprising palladium, platinum or rhodium supported on porous material, and recovering the resultant aminophenol. Preferably the reaction is effected in a temperature range from 25 DEG to 100 DEG C. and a pressure range from 1 to 35 atmospheres. Suitable nitro-phenols are o-, m- and p-nitrophenols, isomeric nitrocresols and other alkyl-substituted nitrophenols, isomeric nitronaphthols, 2-nitroresorcinol and 2,4-dinitrophenol. The catalyst may be supported on charcoal, kieselguhr, or barium sulphate. The product may be recovered from the reaction mixture by acidifying with an inorganic or organic acid and filtering off the precipitated aminophenol crystals.
