prepared, and their characterization was done using NMR and elemental analysis. Their physiochemical properties (thermal stability, viscosity, density, and refractive index) and CO2 solubility (at pressures 1, 5, 10, 15, and 20 bar) were investigated. The cation and alkyl chain effects on the properties and CO2 capturing efficiency were discussed. The thermodynamic functions of solvation were calculated
在当前的工作中,一系列基于-的单阳离子和阳离子型离子液体(三己基十四烷基yl二辛基磺基琥珀酸酯,[P 6,6,6,14 ] DOSS;三辛基十四烷基phosph二辛基磺基琥珀酸酯,[P 8,8,8,14 ] DOSS; 1,6 -双(三辛基phosph)己烷二辛基磺基琥珀酸酯,[P 8,8,8 C 6 P 8,8,8 ] DOSS 2;和1,10-双(三辛基phosph)癸烷二辛基磺基琥珀酸酯,[P 8,8,8 C 10 P 8 ,8,8 ] DOSS 2制备),并使用NMR和元素分析对其进行表征。研究了它们的理化性质(热稳定性,粘度,密度和折射率)和CO 2溶解度(在压力1、5、10、15和20 bar下)。讨论了阳离子和烷基链对性能和CO 2捕集效率的影响。使用亨利定律常数随温度的变化来计算溶剂化的热力学函数。
