More Information
Summary:A process for producing high-purity bisphenol A comprises reacting phenol with acetone in the presence of an acid catalyst to obtain a product mixture, removing the acid catalyst from the product mixture, thereby yielding a liquid mixture, treating the liquid mixture with a weakly basic ion-exchange resin having pyridyl groups as the exchange groups, and purifying the treated liquid mixture. The process does not cause any corrosion of equipment and any decomposition and discoloration of bisphenol A during distillation.
