FIELD: chemistry.
SUBSTANCE: cumane hydroperoxide is decomposed in presence of acid catalyst from sulfated metal in order to transform cumane hydroperoxide into mass, which after decomposition contains mainly phenol and acetone, and mass reaction after decomposition is carried out, preferably without intermediate purification, in presence of cation catalyst, composed of cation-exchange resin and mercaptane promoter or promoter in form of mercaptoalkane acid in order to transform phenol and acetone in mass after decomposition mainly into diphenol A.
EFFECT: high product output with low admixture formation without necessity of stages of intermediate purification.
