As chemical raw material, dimethyl carbonate has become more important because of its environmentally friendly nature. Direct synthesis of dimethyl carbonate with carbon dioxide and methanol is a typical clean synthetic process. The progress of the synthesis of dimethyl carbonate from methanol and carbon dioxide are summarized. It is especially discussed the principle for catalyst design and the action mechanism of different catalyst. The effect of promoter, absorbent agent and reaction condition to catalyst activity and selectivity are discussed.
