WebThe reactor effluent has 95-96% p,p-BPA and 4-5% other reaction products. The phenol to acetone ratio in the feed to the reactor system in an ion-exchange catalyzed BPA manufacturing process has a prominent effect upon by-product formation and reactor effluent color. This in turn effects the material usage and BPA product color quality. WebThe synthesis of bisphenol A (BPA) with heterogeneous catalysts was uivestigated in a batch system and in a plug flow reactor. Gibbs reactor simulations contributed to a better understanding of the reaction which leads to BPA formation.
