The study on dimethyl carbonate synthesis by heterogeneous catalysis

The catalysts used for the synthesis of dimethyl carbonate with propylene carbonate and methanol in an autoclave are investigated.The reaction temperature,ratio of the feeds,concentration of the catalyst and rotational speed of the stirrer and other appropriate reaction conditions are optimized.The obtained result shows that ND6 and ND7 exhibit the highest catalytic activity and their suitable concentrations are 8% 10%(mass),rotational speed is 300rpm,the ratio of methanol to propylene carbonate is 4:1,and the reaction temperature is 60 80℃.
