The solubilities of gases in ionic liquids are important in evaluating ionic liquids as solvents for reactions involving permanent gases, as gas storage media, and as solvents for gas separations. Gas solubilities are also important in developing methods to separate solutes from ionic liquid solutions. Here we describe our measurements of the solubilities of CO2, CH4, C2H 6, C2H 4, O2, and N2 in 1-hexyl-3-methylpyridinium bis(trifluoromethylsulfonyl)imide and compare these results to our previous investigations. In addition, focus is placed on efforts to tailor ionic liquids to enhance the solubilities of some gases, with particular emphasis on carbon dioxide.
气体在离子液体中的溶解度对于评估离子液体作为涉及永久性气体的反应溶剂、气体储存介质以及气体分离溶剂非常重要。气体溶解度在开发从离子液体溶液中分离溶质的方法中也很重要。在此，我们描述了我们对二氧化碳、甲烷、乙烷、乙烯、氧气和氮气在1-己基-3-甲基吡啶双（三氟甲基磺酰）亚胺中的溶解度的测量，并将这些结果与我们之前的研究进行比较。此外，重点在于努力定制离子液体以提高某些气体的溶解度，尤其着重于二氧化碳。
