Abstract: The transesterification of dimethyl carbonate(DMC)and phenol to diphenyl carbonate(DPC)is considered as a clean production route,and this route is usually carried out through two steps. However,in the second step the disproportionation of methyl phenyl carbonate(MPC)usually cannot react thoroughly,which,to a certain degree,have deeply limited the production of the target product DPC. Therefore,the disproportionation of MPC is a key step to synthesize DPC in the transesterification reaction from DMC and phenol and further research of it is of great significance. The reaction thermodynamic,dynamics,catalysts and the synthesis process of the disproportionation of MPC are mainly reviewed. Problems on dynamics and equilibrium constraint of the disproportionation are discussed in details. The proper way to break the equilibrium constraint is to reduce the distillation pressure in the disproportionation and the high selectivity of DPC relies on the property of the catalyst. The main research of the catalyst are supposed to be directed to heterogeneous catalyst. Finally,the perspective and evaluation of domestic researches are given.

Key words: methyl phenyl carbonate, thermodynamics, kinetics, catalyst, process conditions

摘要: 碳酸二甲酯(DMC)与苯酚通过酯交换法合成碳酸二苯酯(DPC)是一条清洁生产路线,该法一般分两步进行,研究发现,其中第二步甲基苯基碳酸酯(MPC)的歧化反应大都不能彻底进行,极大地制约了目标产物DPC的生成,因此,MPC歧化反应作为DMC与苯酚发生酯交换反应生成DPC的关键步骤,对其进行深入的研究有着重要意义。本文综述了MPC歧化反应热力学、动力学、催化剂以及合成工艺方面的研究进展,尤其对MPC歧化反应的动力学问题和平衡限制问题进行了详细讨论,指出打破平衡限制的合理途径是采用减压歧化工艺,而高选择性地生成DPC取决于催化剂的性能,多相催化剂的研究开发应作为今后主要的研究方向。最后对国内研究现状进行了评价和展望,旨在加快我国聚碳酸酯行业的工业化进程。
