Abstract

PURPOSE: To prepare an aminated dihydric phenol, in high selectivity and yield, by heating the corresponding dihydric phenol with ammonia or an amine in liquid phase in the presence of a phenol.
CONSTITUTION: An aminophenol compound or a phenylenediamine compound useful as an additive of pharmaceuticals, pesticides, dyes, rubber chemicals and synthetic resins, or their intermediate, is prepared by reacting a dihydric phenol (e.g. hydroquinone, resorcinol, etc.) with ≥0.5mol, based on 1mol of the phenol, of ammonia, a primary amine (e.g. methylamine) or a secondary amine (e.g. dimethylamine) in a liquid phase at 150W300°C, in the presence of a phenol (e.g. phenol, o-cresol, etc.). The phenylenediamine compound is also useful as a raw material for the production or modification of a special-purpose polyamide.
