Method for preparing ion-exchange resin for use as a catalyst in the synthesis of bisphenols

In the preparation of bisphenol-A by condensation of phenol with acetone in the presence of an acidic ion-exchange resin catalyst, pretreatment of the catalyst to render it free of acidic oligomers which are detrimental to the preparation of bisphenol-A entails washing the catalyst resin with deioni...
