Abstract

(bisphenol A) is purified by prepng. a bisphenol A-phenol addust melting the adduct, and passing the thin liquid melt or soln. through >=1 ion-exchange column contg. an acid and/or a weakly basic ion-exchange resin. The prod. removed from the ion-exchange column is sepd. into phenol and biphenol A by distn. A simple, glass, distn. appts can be used.
