摘要
由CO_(2)和甲醇直接合成碳酸二甲酯(DMC)是典型的绿色合成工艺路线,在碳资源利用和碳减排方面具有重要意义。然而,CO_(2)难以活化且该反应受热力学平衡限制,导致CO_(2)和甲醇的转化率和目标产物收率均偏低,因而阻碍了直接法合成碳酸二甲酯的工业化进程。本文综述了近年来直接法合成碳酸二甲酯的催化剂研究进展,对离子液体、碳酸盐类、过渡金属氧化物、杂多酸和负载型催化剂的设计理论基础、催化性能和催化反应机制等进行了综述。提出开发高效稳定的催化剂仍是现阶段研究的重点,同时耦合经济的原位脱水剂或脱水工艺将是直接法合成碳酸二甲酯工业化实现突破的重要途径。
The direct synthesis of dimethyl carbonate(DMC)from carbon dioxide(CO_(2))and methanol is a typical green synthesis route,which is of great significance in carbon resource utilization and carbon emission reduction.However,CO_(2)is difficult to activate and the direct synthesis of DMC is limited by thermodynamic equilibrium,resulting in low conversion rate of reactants and DMC yield,thus hindering its industrialization process.This article reviewed the research progress in catalysts for the direct synthesis of DMC.The catalyst design,catalytic properties and reaction mechanism of ionic liquids,alkali carbonate,transition metal oxide,heteropoly acid and supported catalysts were reviewed.It is proposed that the development of efficient and stable catalysts is still the focus of current research,and combined with economical in-situ dehydrating agents or dehydration process will be an important way to achieve breakthroughs in the industrialization for direct synthesis of DMC.
