1-氨丙基-3-甲基咪唑溴([APMim]Br)功能型离子液体对CO2具有良好的选择吸收特性,在二氧化碳吸收工程领域将有较好的应用前景.对于[APMim]Br离子液体水溶液体系,只有当水含量足够大才能有效地实现流体对CO2的有效吸收,而且在有效吸收区间(水含量大于55％)水含量多少对溶液体系CO2吸收效率有着非常显著的影响.为此在密闭石英玻璃反应釜内,测定5～75℃,0.1～7.6 MPa范围内,CO2在水的质量分数ω(H2O)为0.5590、0.6578、0.7680和0.8576的[APMim]Br水溶液中的溶解特性.实验结果表明,低压下化学吸收占主导作用,随水含量增大,溶液体系对CO2溶解度成倍增加,而且产生的物理吸收效应远大于离子液体本身的化学吸收能力.在水的质量分数在0.65～0.85区间,[APMim]Br水溶液在相当大的温度和压力范围内具有优良的CO2吸放气特性,显示出良好的工程应用前景.
