ABSTRACT:
A process for the preparation of bisphenols is described which comprises reacting, in a reaction zone, at least 2 moles of a phenol with a carbonyl compound, at a temperature of from 40.degree. to 95.degree. C., in the presence of an acid ion exchanger, optionally partially modified with a compound having an acidic reacting group and a mercaptan group, and recovering the bisphenols from the reaction zone effluent, characterized in that the reaction zone effluent is contacted with an acid ion exchanger in metal salt form and/or a weak base ion exchanger. As a result, it has been found that the formation of undesirable compounds is substantially reduced.
