摘要:
本文介绍了用固体非酸性催化剂活性氧化亚锡催化合成二苯甲酸二甘醇酯的方法。研究了活性氧化亚锡对苯甲酸和二甘醇酯化的催化效果,通过正交实验对反应条件进行了优选,使得在160℃～165℃的温度下反应6小时的酯产率达到98％以上,同时采用有效的后处理方法解决了乳化问题,实际收率94％。
Abstract:
The method of synthesis of diethylene glycol dibenzoate catalyed by solid non-acidic catalyst, active stannous oxide, was introduced in this paper. The catalytic activity of the SnO catalyst for esterification of benzoic acid and diethylene glycol has been studied. The optimum reaction conditions were obtained by orthogonal design. The productive rate of the etser cen reach more than 98% after 6 hrs. reaction at 160-165℃. Meanwhile, the emulsionization problem has been solved by using more effective post-treatment, practical productive rate DEDB is more than 94%.
