In improved isopiestic method, the effect of 1-butyl 1-methylpyrrolidinium trifluoromethanesulfonate ([BMP][TfO]) on the activity of water of aqueous solutions of 1-butyl 3-methyl imidazolium bromide ([BMIm]Br), 1-butyl 3-methyl imidazolium chloride ([BMIm]Cl), 1-hexyl 3-methyl imidazolium bromide ([HMIm]Br), and 1-hexyl 3-methyl imidazolium chloride ([HMIm]Cl) was determined. Some quantities of vapor liquid equilibrium were calculated from the experimental values. The activity coefficients of [BMIm]Br, [BMIm]Cl, [HMIm]Br, and [HMIm]Cl in binary and ternary systems were calculated by the results obtained from correlating the activity of water measured in these systems with TNRF-mNRTL local composition based model. Through it, the transfer of these ionic liquids from water to aqueous ternary solutions containing [BMP][TfO] was investigated with respect to the transfer Gibbs energy. The interactions between solute and solvent were highlighted using the transfer Gibbs energy, water activity and partial pressure of water data.

改进等离子法中1-丁基1-甲基吡咯烷三氟甲磺酸盐([BMP][TfO])对1-丁基3-甲基溴化咪唑([BMIm]Br)、1-丁基水溶液活性的影响测定了 3-甲基氯化咪唑 ([BMIm]Cl)、1-己基 3-甲基溴化咪唑 ([HMIm]Br) 和 1-己基 3-甲基氯化咪唑 ([HMIm]Cl)。从实验值计算出一些量的汽液平衡。[BMIm]Br、[BMIm]Cl、[HMIm]Br 和 [HMIm]Cl 在二元和三元系统中的活度系数是通过将这些系统中测量的水的活度与局部 TNRF-mNRTL 相关的结果计算得出的基于组合的模型。通过这，研究了这些离子液体从水中转移到含有 [BMP][TfO] 的三元水溶液的转移吉布斯能量。使用转移吉布斯能量、水活度和水分压数据突出了溶质和溶剂之间的相互作用。
