Procedure

The process is operated continuously and reaches an equilibrium state after a short time. The partial stream 1 discharged from the process for the preparation of bisphenol A may in principle be any product stream from a process for the preparation of BPA that contains the following components: from 40 to 90 wt. % phenol, from 5 to 40 wt. % bisphenol A and from 5 to 40 wt. % side products formed in the reaction of phenol and acetone to give bisphenol A.
