摘要：

The one-pot synthesis of dimethyl carbonate from propylene oxide, carbon dioxide, and methanol was investigated. The catalyst adopted was a mixture of 1-butyl-3-methylimidazolium tetrafluoroborate ([bmim]BF4) and sodium methoxide. Under the reaction conditions of 4 MPa, 5 h, and 150 degrees C, the conversion of propylene oxide was above 95 %, the selectivity for propylene carbonate was 87.1 %. More importantly, the yield of dimethyl carbonate reached 67.6 %, which is higher than the results of the previous literature using the one-pot synthesis method.
