摘　　要：以磷钼钒杂多酸为催化剂,邻苯二甲酸酐和正丁醇进行反应合成邻苯二甲酸二丁酯(DBP).探讨反应过程中各影响因素,并通过正交试验得出最佳合成条件:邻苯二甲酸酐和正丁醇摩尔配比1∶2.4,反应温度120℃,催化剂用量为邻苯二甲酸酐质量的3%,反应时间2 h,在此条件下DBP产率可达94.20%.The synthesis of dibutyl phthalate（DBP） was made from the reaction between n-butanol and phthalic with molybdovanado-phosphoric heteropoly acids as catalyst. The influential factors of reaction were investigated and the optimized conditions were drawn through orthogonal experiment：molar ratio of n-butyl alcohol to phthalic anhydride was 1 ： 2.4 ; temperature is 120℃ ; Catalyst＇ s weight was 3 % of phthalic anhydride＇s weight,and reaction time was 2 h. The yield of DBP is about 94.20%.
