摘要
综述了近年来国内外碳酸乙烯酯或碳酸丙烯酯与甲醇酯交换合成碳酸二甲酯催化剂的研究进展,重点对金属氧化物催化剂、离子交换树脂和负载型催化剂等多相催化剂的制备和催化性能作了介绍。金属氧化物催化剂在使用过程中可能发生化学变化,催化寿命较短;离子交换树脂对热稳定性较差,不能在高温下长期使用;负载型催化剂活性组分的流失有待解决。尽管存在这些不足,但多相催化剂分离简单,容易实现反应-分离一体化,是今后研究开发的主要方向。
Latest researches in the catalysts for synthesis of dimethyl carbonate（DMC） from ethylene carbonate （or propylene carbonate） and methanol were reviewed, especially the preparation and catalytic properties of heterogeneous catalysts, such catalysts. The life cycle of metal oxide catalysts is as metal oxides, ion exchange resins and supported shorter due to chemical reactions occurring during operation. The stability of ion exchange resins is relatively poor and can not be used at high temperature for long term. Loss of active components is a problem with supported catalysts. Heterogeneous catalysts, featuring easy separation from the products, represent the trend in this field.
