Bisphenol A from Phenol and Acetone With an Ion Exchange Resin Catalyst—Union Carbide Technology
PEP Review 82-1-1
Published September 1982
Bisphenol-A is produced commercially by the acid catalyzed condensation of phenol and acetone under mild conditions of temperature and pressure. This review evaluates the use of a cation exchange resin condensation catalyst according to Union Carbide technology. The process avoids the handling of highly corrosive streams usual in traditional HCl catalyzed processes and appears to be capable of producing very high purity polycarbonate grade bisphenol-A simply.
Compared with the HCl catalyzed process, the resin catalyzed process has a 2-3�/lb lower net production cost for polycarbonate grade product. Production costs for epoxy grade product are the same for both processes. The resin catalyzed process shows a higher return on investment for both polycarbonate and epoxy grade products.
