Patent number: 5777180Abstract: An improved process for the production of bisphenols is presented in which ketones and phenols are reacted in the presence of an acidic cationic exchange resin catalyst and a mercaptan cocatalyst. Prior to the reaction, alkyl alcohol is removed from the ketone stream. Cocatalyst is withdrawn from the reactor so that cocatalyst derivatives such as disulphide ions can be removed from the presence of the catalyst thereby reducing the possibility of catalyst poisoning.Type: GrantFiled: December 18, 1996Date of Patent: July 7, 1998Assignee: Shell Oil CompanyInventors: Raymond Lawrence June, Robert Lawrence Blackbourn, Edgar Donald Allan, James Laurel Buechele
