摘要： 聚苯乙烯交联白球(含二乙烯基苯7％)与四氯化锡反应可制成一种稳定的高分子载体Lewis酸催化剂,它对酯化、缩醛、缩酮、成醚和付氏烷基化等有机合成反应都具有较高的催化效能,这种高分子载体催化剂不仅催化效率高、性能稳定,而且制备简单,使用操作方便,易于从反应体系中分离,无污染,是一种很有前途的新型催化剂。

Abstract: Stannic chloride is protected with polystyrene-divinylbenzene (7%) copolyme beads in CS2 to form a stable complex containing 10.8% of chlorine. The SnCl4 supported by the polystyrene is resistant to water and is Prolonged Storing in air at least one year. The complex catalyst (PS-SnCl4) is a strong solid Lewis acid. The Lewis acid supported by polymer can be used to catalyze a lot of organic synthetic reactions in high yield, such as esterfications, acetal formations, ketal formations, etherifications and Friedel-Crafts alkylations.
