SYNTHESIS OF BENZYLIDENE ACETONE CATALYZED BY TRIBUTYL AMINE AMINATING STRONGLY BASIC ANION EXCHANGE RESIN

Macro-porous tributyl amine aminating strongly basic anion exchange resin-a phase transfer catalyst with high catalytic activity for nucleophilic substitution under basic condition, which was screened out via combinatorial chemistry method --was used to catalyze the aldol condensation reaction for synthesis of benzylidene acetate. Influence of the reaction condition for the yield of benzylidene acetone was .investigated, and the reaction condition was optimized. Under the optimum reaction condition, the yield amounted to 98%.
