摘要
根据萃取精馏原理 ,采用正交试验设计 ,运用计算机对实验数据进行最优化处理 ,确定了萃取精馏甲醇与碳酸二甲酯共沸物分离的最佳工艺条件。以此工艺路线分离所得的碳酸二甲酯纯度为 99.92 %。
Extractive distillation of DMC from its azeotrope with methanol using optimization was studied. It was found that extracting agent, filler, evaporation, reflux ratio remarkably influenced the separation effect of azeotrope. Optimum conditions of processing were determined by the experiments and the purity of DMC was 99.92%.
