| 英文摘要 | We systematically screened binary catalysts for synthesis of dimethyl carbonate (DMC) from CO(2), CH(3)OH and ethylene oxide (EO) in the presence of H(2)O by two-step transesterification process, and found the commercial quaternary ammonium salts/K(2)CO(3), pyridinium salts/K(2)CO(3) and KI/K(2)CO(3) were effective binary catalysts for two-step synthesis of DMC with no need for separation of ethylene carbonate (EC). Near 100% conversion of EO and 82% yield of DMC were obtained under mild reaction conditions. However, the imidazolium salts were not compatible with inorganic alkaline possibly because of the reactive C(2)-H in the imidazolium ring. Furthermore, the KI/K(2)CO(3) could be easily recovered and reused 12 times without obvious loss of its catalytic activity. The process avoids EC separation, and represents a simple, ecologically safer, cost-effective and energy-saving route for synthesis of DMC with high product quality, as well as easy catalyst recycling. |
