CATALYST FOR CONDENSATION REACTIONS; JETTED, SUSPENSION-POLYMERISED, CROSS-LINKED, STYRENIC COPOLYMER BEADS FUNCTIONALISED WITH ACIDIC CATION-EXCHANGE GROUPS

摘要

Strongly acidic cation-exchange resin beads made by functionalizing jetted, suspension-polymerized, crosslinked, styrenic copolymer beads with sulfonic acid groups have been found to produce an unexpectedly high level of conversion when catalyzing condensation reactions, particularly the condensation of phenol with aldehydes or ketones to form bisphenols.
