论文摘要
新型任务特异性离子液体（ILS）的发展代表了现代有机和物理化学中的基本挑战。最近，我们报道了表面活性IL，其中包含两个众所周知的有机阳离子（1-丁基-3-甲基咪唑唑和四丁基铵）和两个表面活性阴离子（Lauryl硫酸盐，Lauryl硫酸盐）。在目前的工作中，我们研究了这些离子化合物与所选择的实际意义的小分子的亲和力：水，氟化氢，硫酸氢氢和二氧化碳。我们确定硫酸盐基团，醚基和芳族咪唑环对极性气体分子的物理吸附做出了最大的贡献。反过来，四丁基铵阳离子，阴离子的饱和碳氢化合物链和1-丁基-3-甲基咪唑唑的烷基链的贡献显着较小。在使用石油工业中使用表面活性IL来捕获和存储不良和有毒气体的情况下，报告的数据很有趣。
The development of novel task-specific ionic liquids (ILs) represents an essential challenge in modern organic and physical chemistries. Recently we reported surface-active ILs contained the two well-known organic cations (1-butyl-3-methylimidazolium and tetrabutylammonium) and the two surface-active anions (lauryl sulfate, lauryl ether sulfate). In the present work, we investigate the affinity of these ionic compounds to the selected small molecules that exhibit practical implications: water, hydrogen fluoride, hydrogen sulfate, and carbon dioxide. We identified that the sulfate group, the ether groups, and the aromatic imidazole ring make the strongest contributions to the physical sorption of the polar gas molecules. In turn, the tetrabutylammonium cation, the saturated hydrocarbon chain of the anions, and the alkyl chains of 1-butyl-3-methylimidazolium contribute to a significantly smaller extent. The reported data are interesting in the context of using surface-active ILs in the oil industry to capture and store undesirable and toxic gases.
