摘要:通过对碳酸二甲酯(DMC)与苯酚酯交换法反应蒸馏合成碳酸二苯酯(DPC)的研究,筛选合适的催化剂和寻找最佳的工艺条件,为DPC的工业化打下基础。实验结果表明,在常压下,温度145℃,原料配比n(PhOH)∶n(DMC)=3∶1,n(PhOH)∶n(催化剂)=1∶0.012,反应时间10h,碳酸二甲酯总转化率为32.04%,DPC产率为18.00%,碳酸苯甲酯(MPC)产率为14.04%,DPC的选择性为56.18%,而且无苯甲醚和CO2生成,所选催化剂二丁基二月桂酸锡的催化性能明显优于路易斯酸。
Diphenyl carbonate(DPC) was synthesized by transesterification of dimethyl carbonate(DMC) with phenol in the presence of dibutyltin dilaurate catalyst under reactive distillation condition. At atmospheric pressure, n(PhOH)∶n(DMC)=3∶1, n(PhOH)∶n(catalyst)=1∶0.012, at temprature of 145 ℃ and with the reaction time being 10 h, the total coversion rate of DMC was (32.04%),the yield of DPC 18.00% , and the selectivity of PDC 56.18%. No anisol was observed in the product mixture.
