摘要

wanglp_csu@163.com关键词:聚碳酸酯二醇;二苯caebonate;1、4-Butyldiol;金属醋酸盐;酯交换抽象。在醋酸金属催化剂的存在下，以碳酸二苯酯和1,4-丁基二醇为原料合成聚碳酸酯二醇。碱金属醋酸盐和碱土金属醋酸盐催化剂表现出较高的催化活性，其中乙酸锂催化剂活性最高。并对催化机理进行了探讨。

Catalytic activity of metal acetate in transesterification of diphenyl carbonate and 1,4-butyldiol

wanglp_csu@163.com Keywords: Polycarbonate diols; Diphenyl caebonate; 1,4-Butyldiol; Metal acetate; transesterification Abstract. Synthesis of polycarbonate diols from diphenyl carbonate and 1,4-butyl diol has been demonstrated in the presence of metal acetate catalysts. Alkali metal acetate and alkaline earth metal acetate catalysts showed much higher catalytic activity, of them, lithium acetate was the most active. And the catalytic mechanism was discussed.
