In the present study, to investigate the soluting effect in ternary aqueous solutions of ionic liquids (ILs), experimental studies have been carried out on ionic liquid 1 + ionic liquid 2 + water systems that are in isopiestic equilibrium. The imidazolium-based ionic liquids 1-ethyl-3-methyl-imidazolium bromide ([C2MIM]Br), 1-butyl-3-methylimidazolium bromide ([C4MIM]Br), and 1-hexyl-3-methylimidazolium bromide ([C6MIM]Br) were selected, and the vapor–liquid equilibria (VLE) of {[C2MIM]Br + [C6MIM]Br + water}, {[C2MIM]Br + [C4MIM]Br + water}, and {[C4MIM]Br + [C6MIM]Br + water} were investigated by the isopiestic method. The equations derived from the Zdanovskii–Stokes–Robinson rule were applied to predict the thermodynamic properties (density, speed of sound, and surface tension) of ternary solutions from the corresponding data of binary subsystems with the same water activity data, and the calculated thermodynamic properties were compared to the experimental data.

在本研究中，为了研究离子液体（ILs）在三元水溶液中的溶出效果，已经对处于等浓度平衡的离子液体1 +离子液体2 +水系统进行了实验研究。咪唑基离子液体1-乙基-3-甲基咪唑溴化物（[C 2 MIM] Br），1-丁基-3-甲基咪唑溴化物（[C 4 MIM] Br）和1-己基-3-甲基咪唑鎓选择溴化物（[C 6 MIM] Br），{{C 2 MIM] Br + [C 6 MIM] Br +水}，{[C 2 MIM] Br + [C 4 MIM] Br +水}和{[C 4 MIM] Br + [C 6用等渗方法研究了MIM] Br +水}。使用Zdanovskii–Stokes–Robinson规则得出的方程式，根据具有相同水活度数据的二元子系统的相应数据，预测三元溶液的热力学性质（密度，声速和表面张力）。性能与实验数据进行了比较。
