非光气法催化合成碳酸二苯酯研究进展

摘要

This paper is aimed to review the recent progress in catalytic synthesis of diphenyl carbonate (DPC) by four non-phosgene routes,i.e. transesterification,oxidative carbonylation of phenol, transesterification-decarbonylation of dimethyl oxalate and phenolysis of urea. The review mainly focuses on the catalyst,the reaction condition,conversion of the reactant and the yield of product for each non-phosgene route,the advantages and disadvantages of which are described. Two routes, transesterification and phenolysis of urea,are preferred based on the comparison of raw materials, catalyst preparation,technology,and the energy consumption for four routes,so,these two routes may be dominant in future.%综述了近年来酯交换法、苯酚氧化羰化法、草酸二甲酯和苯酚交换、脱羰法和尿素酚解法4种非光气法催化合成碳酸二苯酯（DPC）的研究进展，包括每种合成法所使用的催化剂、反应条件、反应物的转化率和产物的收率，指出了每种合成法的优缺点，并从原料来源的难易、催化剂制备的成本、产物的收率、生产工艺的复杂性、能耗等方面进行分析比较，指出选用酯交换法和尿素酚解法生产碳酸二苯酯较为有利，这两种合成法可能是未来研究的重点。
