| Abstract: | A process of synthesizing methyl acetate by reactive distillation with acetic aid and methanol as starting materials and sulfuric acid as catalyst was studied. Some factors such as reflux ratio,mole fraction of acetic acid in feed-in material,number of trays,feed-in position of mixed acid and others,which effect the conversion rate of acetic acid and the purity of methyl acetate at the top of tower,were mainly investigated.The optimum condition was obtained. |
