Bisphenol A (BPA) is a chemical building block used for the production of epoxy resins and durable polycarbonate. Bisphenol A (BPA) is synthesized by condensation of acetone with phenol. Hydrochloric acid can be used as a catalyst.
The use of pure monomer Bisphenol A (BPA) without presence of impurities will result in a polycarbonate with consistent properties.

The highly automated continuous suspension based melt crystallization process applied for Bisphenol A (BPA) will ensure low energy consumption at low operator attention. Crystallization of BPA adduct (BPA + phenol) allows for lower temperature operation and can improve the energy efficiency of the process while still maintaining high purity BPA production. Crystallization is a proven industrial purification technique and GEA Messo PT has been active in its application on a variety of products for over 30 years. Bisphenol A (BPA) purification is one of the new feasible applications.
