CO_2直接合成碳酸二甲酯催化剂的研究进展

碳酸二甲酯(DMC)是一种重要的绿色化工原料,在工业、农业、医药行业等领域得到广泛的应用。碳酸二甲酯的合成方法有多种,其中光气甲醇法、酯交换法、氧化羰基化法已经工业化,但由于各自的缺点,限制了其规模化。近年来,研究较多的也是公认最绿色环保的合成方法是用二氧化碳与甲醇直接合成碳酸二甲酯。介绍了这种方法所应用的催化剂及其催化机理研究的进展状况,并对诸多催化剂存在的问题提出建议。

Research progress of catalyst for direct synthesis of dimethyl carbonate from carbon dioxide

Dimethyl carbonate(DMC) is an important green chemical material,and it has been applied widely in industry,agriculture and pharmaceutical industry.DMC has a variety of synthetic methods,of which the phosgene methanol method,transesterification method and oxidation carbonylation have been industrialized,but their own shortcomings limit their scale.In recent years,the method of synthesizing DMC using carbon dioxide and methanol is researched and regarded as the greenest synthetic method.The application of cat...
