ABSTRACT:
A method for producing bisphenol includes introducing a phenol and a ketone into a fixed, supported catalytic bed reactor system in a downflow mode, reacting the phenol and the ketone to form a reaction mixture, and recovering the bisphenol isomer from the reaction mixture. The preferred bisphenol isomer is bisphenol A, or p,p′-bisphenol A, produced from the reaction of phenol and acetone. The reactor for producing the bisphenol A from the reaction of phenol and acetone includes an ion exchange resin catalyst disposed in a bed and packing randomly distributed throughout the ion exchange resin catalyst to improve heat transfer efficiency and reduce compression of the catalyst bed.
