Hydroxyl-functionalized ionic liquids 1-(2-hydroxyethyl)-3-methylimidazolium alanine was synthesized and characterized by ¹H NMR and ¹³C NMR spectrum. And it was mixed with DMSO and water respectively by weight method over the entire concentration. The density, viscosity, surface tension and refractive indices of the binary mixture were measured in the temperature range from 288.15 K to 333.15 K. Then volume properties and excess data were calculated and fitted. According to Redlich-Kister equation, the relationship between excess molar volume, viscosity deviation and the molar fraction of solute were fitted. Using the excess properties, the influence of the interaction between IL and solvents (DMSO/water) were analyzed. By comparing with the systems of the different ILs in the same solvents, the above-mentioned properties were discussed.

合成羟基官能化离子液体1-(2-羟乙基)-3-甲基咪唑鎓丙氨酸，并通过¹ H NMR 和¹³C核磁共振谱。并在整个浓度范围内按重量法分别与DMSO和水混合。在 288.15 K 至 333.15 K 的温度范围内测量二元混合物的密度、粘度、表面张力和折射率。然后计算并拟合体积特性和过量数据。根据Redlich-Kister方程，拟合了过量摩尔体积、粘度偏差与溶质摩尔分数之间的关系。使用多余的特性，分析了离子液体和溶剂（DMSO/水）之间相互作用的影响。通过与相同溶剂中不同离子液体的体系进行比较，讨论了上述性质。
