Abstract

A process for preparing an adduct of a biphenol with a phenolic compound comprising the following steps: (a) reacting a carbonyl compound with a stoichiometric excess of a phenolic compound is the presence of an acidic cation exchange resin as a catalyst, to produce a product mixture containing a biphenol, unreacted phenolic compound, unreacted carbonyl compound and water; and (b) crystallizing an adduct of the biphenol with the phenolic compound from the product mixture in a crystallization device in the presence of water and acetone. The product mixture obtained in step (a) is not subjected to a distillation step before the product mixture enters the crystallization device and prior to the crystallization step (b) the content of the carbonyl compound in the product mixture is controlled and, if necessary, carbonyl compound is added such that the total concentration of the carbonyl compound is from 0.1 to 8%, based on the total weight of the product mixture.
