CO气相偶联制草酸酯研究进展

摘要

CO气相偶联法制备草酸酯具有条件温和、安全环保和原料丰富等特点.综述了CO气相偶联制草酸酯的研究进展,分别从工艺流程、催化剂制备、催化剂失活和偶联反应机理等方面介绍,并对偶联法的发展前景进行了展望.%The gas phase CO coupling method is considered as a safe,environmentally-friendly and economic route to produce oxalic ester because of its mild reaction conditions and richness of raw material sources.The research progress in gas phase CO coupling method was reviewed,including technological process,preparation and deactivation of the catalysts and the mechanism of the coupling reaction.The development prospect of CO coupling method is outlined.
