Abstract

The density and viscosity of the pseudo-binary mixtures of eutectic solvent (ES) composed of choline chloride and ethylene glycol ([ChCl/EG]) with dimethylsulfoxide (DMSO) were measured. In order to understand the effect of the mole ratio of ChCl:EG, two ChCl/EG ESs with the mole ratio of 1:3 and 1:4 (abbreviated as [ChCl/EG]_(1:3) and [ChCl/EG]_(1:4) in this work) were prepared. The measurements were carried out by digital vibrating U-tube density meter and Ubbelohde capillary viscometer from 303.15 to 323.15 K at atmospheric pressure (98.5 kPa). The Jouyban–Acree model was applied to correlate the experimental density and viscosity data of DMSO/[ChCl/EG]_(1:3) and DMSO/[ChCl/EG]_(1:4) mixtures. In addition, based on the experimental data, the derived properties of the mixtures, such as excess molar volume and viscosity deviation, were calculated. The comparison and analysis of excess molar volume and viscosity deviation for DMSO/[ChCl/EG]_(1:2) reported in literature and the results obtained in this work were carried out.

二甲基亚砜与氯化胆碱/乙二醇共晶溶剂混合物的密度和粘度

测量了由氯化胆碱和乙二醇（[ChCl/EG]）组成的共晶溶剂（ES）与二甲基亚砜（DMSO）的假二元混合物的密度和粘度。为了了解 ChCl:EG 摩尔比的影响，制备了两种摩尔比为 1:3 和 1:4 的 ChCl/EG ES（本文中简称为 [ChCl/EG](1:3) 和 [ChCl/EG](1:4)）。在 303.15 至 323.15 K、常压（98.5 kPa）条件下，使用数字振动 U 型管密度计和 Ubbelohde 毛细管粘度计进行测量。应用 Jouyban-Acree 模型对 DMSO/[ChCl/EG](1:3)和 DMSO/[ChCl/EG](1:4)混合物的实验密度和粘度数据进行了相关分析。此外，还根据实验数据计算了混合物的推导性质，如过量摩尔体积和粘度偏差。对文献报道的 DMSO/[ChCl/EG](1:2)过剩摩尔体积和粘度偏差与本研究的结果进行了比较和分析。

期刊介绍： Journal of Solution Chemistry offers a forum for research on the physical chemistry of liquid solutions in such fields as physical chemistry, chemical physics, molecular biology, statistical mechanics, biochemistry, and biophysics. The emphasis is on papers in which the solvent plays a dominant rather than incidental role. Featured topics include experimental investigations of the dielectric, spectroscopic, thermodynamic, transport, or relaxation properties of both electrolytes and nonelectrolytes in liquid solutions.
