Method and catalyst for making bisphenol

A sulfonated aromatic organic polymer, such as sulfonated polystyrene ion-exchange resin, is provided having N-alkylaminoorgano mercaptan groups attached to backbone sulfonyl radicals by covalent nitrogen-sulfur linkages. The ion-exchange resin can be used to effect phenol-ketone condensation in the...

Zusammenfassung:	A sulfonated aromatic organic polymer, such as sulfonated polystyrene ion-exchange resin, is provided having N-alkylaminoorgano mercaptan groups attached to backbone sulfonyl radicals by covalent nitrogen-sulfur linkages. The ion-exchange resin can be used to effect phenol-ketone condensation in the synthesis of bisphenols.
