由二氧化碳出发合成有机碳酸酯

对以二氧化碳为原料合成有机碳酸酯的环氧路线、酯交换和直接合成方法作了综合评述 ,认为直接合成是最佳的合成路线。碳酸酯的直接合成可在均相及多相催化体系中进行 ,负载金属、金属甲氧基化合物及碱均可作为催化剂。直接法研究的关键在于高性能催化剂的开发、由二氧化碳对金属 -氧键插入反应导致的催化循环的构筑及耦合反应的应用。

Synthesis of organic carbonates from carbon dioxide

Studies on the synthesis of organic carbonates from carbon dioxide including epoxidation, ester interchange and direct method are reviewed. It is pointed out that the direct method is the optimal synthesis route. The direct synthesis of carbonates can be carried out both in homogeneous and heterogeneous catalytic systems. Supported metals, metal methoxides and bases can all be used as catalysts. Key points in the research of the direct method include the development of high effect catalysts, the design of catalytic cycle caused by the insertion of carbon dioxide into metal oxygen bond and the application of coupling reaction.
