Bisphenol A (BPA) is an important industrial chemical used primarily in the production of polycarbonate plastics and epoxy resins. The technology for its industrial production involves several key steps, primarily starting with the reaction of acetone and phenol. This Ion-exchange resin-catalyzed process is a modern and more environmentally - friendly approach. Cation - exchange resins are used as catalysts. The reaction of phenol and acetone occurs in a reactor filled with the resin catalyst. The reaction temperature and other conditions are carefully controlled to ensure high conversion rates. After the reaction, the product mixture is separated through methods like distillation and crystallization.
