离子交换与吸附

以用组合化学方法筛选出的在有外加碱条件下的亲核取代催化活性最高的聚合物季铵 盐－大孔型苯乙烯系三丁胺胺化强碱性阴离子交换树脂为相转移催化剂，催化合成苄叉丙酮， 考察了各种反应条件对苄叉丙酮收率的影响，在优化反应条件下，苄叉丙酮的收率高达９８％， 且催化剂可重复使用。

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%.
