采用自制的功能离子液体1-2-胺乙基丁基咪唑溴盐([ NH2 ebim ] Br )、1-2-胺乙基甲基咪唑溴盐([ NH2 emim] Br)的水溶液作为吸收剂,进行吸收CO2的研究。考察了不同浓度的功能离子液体水溶液吸收CO2的吸收速率,温度对CO2的吸收速率的影响,不同功能离子液体水溶液对吸收速率的影响,以及吸收剂的再生效率,并探讨了功能离子液体水溶液吸收CO2的机理。结果表明,功能离子液体水溶液实现了对CO2的化学吸收,吸收速率随着功能离子液体浓度和温度的增加而增加,而功能离子液体阳离子碳链长短对水溶液吸收CO2的速率影响不显著。实验中每摩尔功能离子液体吸收的CO2大于0.5 mol,其反应机理被提出。

Task-special ionic liquid,[ NH2 ebim] Br,[ NH2 emim] Br prepared by self-made were dissolved in water. The aqueous solution of task-special ionic liquid was used as absorbent to absorb CO2 . The CO2 absorption rates under different conditions were investigated,such as different concentrations of task-spe-cial ionic liquid,different operating temperatures,and different ionic liquids with different carbon numbers in the cation. The results show that the aqueous solution of task-special ionic liquid can absorb CO2 ,and absorption rates increase with the increase of ionic liquid concentrations and the operating temperature. The carbon number in the cation of task-special ionic liquid has no effect on the absorption rates. CO2 amount absorbed per molar task-special ionic liquid is more than 0. 5 mol. The absorption mechanism of task-special ionic liquid aqueous solution is proposed.
