几种新型的2-羟甲基功能化离子液体催化剂可以在不使用任何助催化剂或有机溶剂的情况下,由二氧化碳和环氧化物合成环状碳酸酯。此外,2-羟甲基功能化的离子液体与碱是相容的,与K2CO3结合可作为CO2经碳酸亚乙酯绿色合成碳酸二甲酯的有效催化体系,无需催化剂分离。此外,还用密度泛函理论解释了2-羟甲基功能化离子液体催化CO_2固定环状碳酸酯的机理。这里报道的过程代表了一种简单、生态安全、成本效益高和节能的从二氧化碳制备有机碳酸盐的方法。
Several novel 2-hydroxymethyl-functionalized ILs act as the catalysts for synthesis of cyclic carbonates from CO2 and epoxides without the use of any co-catalysts or organic solvent. Moreover, the 2-hydroxymethyl-functionalized ILs were compatible with base, which combined with K2CO3 were used as effective catalytic system for green synthesis of dimethyl carbonate from CO2via ethylene carbonate without catalyst separation. Additionally, the mechanistic details of the fixation of CO2 into cyclic carbonate catalyzed by 2-hydroxymethyl-functionalized ILs were also elucidated by density functional theory. The process reported here represents a simple, ecologically safer, cost-effective and energy-saving route to organic carbonates from CO2.
