摘要
本文是用季铵盐类相转移催化剂连接到二乙烯基苯交联的聚苯乙烯上,形成不溶性的固体高分子相转移催化剂,应用这种固体催化剂于水和甲苯体系中,三相反应成功地合成了三种苄酯。这种三相催化反应比经典合成方法,具有条件温和,操作简单,更主要的能回收催化剂,经再生处理后能重复使用,再生率是满意的。 反应结果及对产物熔、沸点、红外光谱的测定表明:三相催化合成苄酯是一种行之有效的有机合成新方法。
Benzyl benzoate, benzyl acetate, P-nitrobenzyl benzoate were prepared by reaction of benzyl chloride or P-nitrobenzyl chloride with organic salts (sodium acetate or sodium benzoate) in toluene / H2O containing polystyrene bound quaternary ammonium salts as phase transfer catalysts. The present proceduce has the advantages of simplicity in operation.The caatalysts can be separated easily from reaction mixtures and can be reused.
