measurement was carried out as a function of molality (0.05 to 1.0 mol∙kg-1) and temperature from 293.15 to 328.15 K under atmospheric pressure. The binary systems contained the ILs [TMGH]+[C8H15O2]-, [TMGH]+[C10H19O2]- and [TMGH]+[C12H23O2]-. The apparent molar volume (Vϕ) and the apparent molar isentropic compressibility (Ks,∅)were calculated using the experimental data and a Redlich-Mayer type equation was
含有不同羧酸根阴离子、辛酸根 (C 8 H 15 O 2 ) -、癸酸根 (C 10 H 19 O 2 ) -和月桂酸根 (C 12 H 23 O 2 ) -, 在二甲基亚砜 (DMSO) 和二甲基甲酰胺 (DMF) 中通过表观摩尔性质进行检查。在这项工作中,选择了三种离子液体,因为它们具有质子性并与极性溶剂相互作用,从而影响热物理性质。我们测量了热物理性质以研究离子-离子和离子-溶剂之间的相互作用,并通过密度和声速的实验测量分析了离子液体阴离子和温度的影响。在大气压下,作为摩尔浓度(0.05 至 1.0 mol ∙ kg -1)和温度 293.15 至 328.15 K的函数进行测量。二元系统包含 ILs [TMGH] + [C 8 H 15 O 2 ] -, [TMGH] + [C 10 H 19 O 2 ] -和 [TMGH] + [C 12 H 23 O 2 ] -。表观摩尔体积 (
