ABSTRACT:
An improved process for obtaining bisphenols by reaction of a phenol, or substituted phenol having a hydrogen in the para position, and an alkenyl ether, wherein the unsaturation in the ether is in the alpha position, in the presence of a strong acid catalyst. The process gives particularly good results when bisisopropenyl ether is reacted with phenol in the presence of a strong acid cation exchange resin in which part of the exchange sites have been neutralized with 2,2-dimethylthiazolidine.
