摘要：

Amino-functionalized task-specific ionic liquids are thought to have good application prospects in terms of CO2 fixation and separation, due to their strong CO2 absorption with selectivity under ambient conditions. In this study, four task-specific ionic liquids were synthesized, with their structures and properties characterized by IR, 1H NMR. The performances of these four task-specific ionic liquids in terms of CO2 absorption and regeneration were investigated. It was found that these four task-specific ionic liquids are supervisor to traditional ionic liquids in terms of CO2 absorption. In addition, these four task-specific ionic liquids showed excellent regeneration performance, which indicated that they could be reused for CO2 absorption. The solubility of CO2 in ionic liquids was affected significantly by the viscosity, decreased by increasing the temperature, increased by increasing the pressure and absorbent concentration. Enhanced mass transfer can improve the regeneration efficiency. However, no significant effect on the absorption properties of ionic liquids was observed after multiple regenerations. © All Right Reserved.
