摘　　要：用硅钨杂多酸催化合成了增塑剂戊二酸二异辛酯。对催化剂的制备条件和戊二酸二异辛酯的合成条件进行了研究。在最佳反应条件下,酯化率可达98%以上。The synthesis of diisooctyl glutarate by esterification of glutarie acid with isooctryl alcohol by heteropoly acid was proposed in this paper. The preparation conditions of the complex catalysts and esterification conditions were studied. Under the optimum synthesis condition, the esterification yield were over 98%.
