| 摘 要： | 室温离子液体是一种“绿色溶剂”,具有独特的气体溶解选择性.基于正规溶液理论,根据文献发表的常规咪唑盐离子液体对不同气体的溶解度数据,结合基团贡献法预测了常压下CO2、CH4、N2、CO在含氰基、醚键等极性基团的咪唑盐离子液体中的亨利系数,进而得到不同气体在该类离子液体中的溶解选择性.结果表明,极性基团的引入有助于提高咪...

| Abstract: | Room temperature ionic liquid(RTIL),known as a kind of green solvent,has preferential solubility for some specific gases.Recent studies showed that high separation performance of CO2 could be obtained by using imidazolium-based ionic liquid.Based on regular solution theory and the solubility data of different gases in imidazolium-RTIL available in literature,a group contribution method was used to predict the solubility of CO2,CH4,N2,CO and corresponding solubility selectivity under ambient pressure in imid... |
