摘要

Promotion of ionic liquid,1-ethyl-3-methylimidazolium bromide (emimBr),to the synthesis of dimethyl carbonate (DMC) from methanol and carbon dioxide in the presence of potassium carbonate and less amount of methyl iodide under mild conditions was investigated.The results showed that the high selectivity and raised yield of DMC was achieved due to the addition of emimBr in the reaction system.And effect of several reaction conditions such as temperature,pressure and amount of emimBr was discussed.
