Jones–Dole equation and Vand’s equations. Positive viscosity A and B coefficients were observed for both studied ILs, while the D coefficients were also found to be necessary, showing specific behavior depending upon the solute–solute interactions. Calculations of the B coefficients for anions are reported. The application of Vand’s equation to the viscosity data enabled us to calculate the Einstein–Simha
离子液体 (ILs) 1,3-二甲基咪唑甲基硫酸盐 [MIm][MeSO4] 和 1-乙基-3-甲基咪唑乙基硫酸盐 [EMIm][EtSO4] 已合成并通过 1H NMR、13C NMR、质谱光谱法、TGA 和 DSC 方法。[MIm][MeSO4](0.02458 至 0.18922 mol·kg-1)和 [EMIm][EtSO4](0.01044 至 0.21261 mol·kg-1)的二元水溶液的密度和粘度报告在 (293.15, 5 和 298) 303.15) K 和在环境压力下。在所研究的浓度下计算所研究的 IL 的表观和部分摩尔体积。所研究的离子液体的极限部分摩尔体积是使用适当的外推方法获得的。还获得了 298.15 K 时的极限表观摩尔膨胀率值。通过应用琼斯-多尔方程和范德方程来分析相对粘度数据。对于两个研究的 IL,观察到正粘度 A 和 B 系数,而 D 系数也被发现是必要的,显示出取决于溶质
