摘要
碳酸二甲酯是一种重要的绿色化工原料,其合成路线正朝着简单化、无毒化和无污染化的方向发展,以二氧化碳和甲醇一步法直接合成碳酸二甲酯在合成化学、碳资源循环利用和环境保护方面都具有重要意义。该文综述了近年来二氧化碳和甲醇直接合成碳酸二甲酯的研究开发最新进展,对不同催化体系的设计理论基础、催化反应机理、催化工艺技术以及催化性能等进行了评述。二氧化碳和甲醇直接合成碳酸二甲酯反应过程中受热力学和反应物有效活化程度的影响存在着催化剂活性或选择性不高,产率低等技术屏颈,着眼于将来产业化的可能性,重点讨论了目前不同催化体系的优缺点,为今后寻找更加合适的催化活性组分及载体进行理论分析,不断提高催化剂的活性和选择性。
As an important chemical raw material,the synthetic routes of dimethyl carbonate（DMC） have been developed toward the simple,non-toxic and non-pollution methods.It is proposed that one-step synthesis of DMC from carbon dioxide,especially from carbon dioxide and methanol,has the most significance in the fields of synthetic chemistry,utilization of carbon resources as well as environmental protection.Recent progress in the synthesis of DMC from carbon dioxide and methanol is reviewed with special focus on the design principle,reaction mechanism,technology and catalytic properties of different catalyst systems.Due to the unfavorable thermodynamics of the reaction and the ineffectively activation of reactants in the synthesis of DMC from carbon dioxide and methanol,the current catalysts generally result in low yield and selectivity of DMC,which in turn lead to the most big hurdle for the industrializing feasibility of this technology.In this connection,it is the most important to look for even highly active catalysts together with corresponding carriers for the direct synthesis of DMC from carbon dioxide and methanol.
