| Abstract imethyl carbonate has been synthesized by transesterification of methanol with propylene carbonate using CHS—1 and CHS—2 as catalysts.The effect of amount of catalyst and weight ratios of methanol to propylene carbonate et al.on the yield of transesterification have been studied.The experimental results showed that the optimum conditions are:the amount of catalyst 0.4%～0.5%,weight ratio of methanol to propylene carbonate 8～10 and reaction time 40～60 minutes.This process of transesterification by reactive distillation is of value in industrial production. |
