| Abstract: | 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%. |
