Using phthalic anhydried, butyl alcohol and henzyl chloride as raw materials, butyl benzyl pthalate (BBP)is synthesized by phase transfer catalysis. The optimum reaction conditions are determined. The process is simple with high yield of BBP.

• 研究了以邻苯二甲酸酐、正丁醇和氯化苄为原料，用相转移催化法合成邻苯二甲酸丁苄酯的最适宜反应条件，讨论了投料比、反应温度、反应时间及催化剂用量和种类对酯收率的影响，该工艺简单，成本低，酯收率高。
