In the development of CO2 capture and utilization, the physical and transport properties of the binary systems are significant, because these can affect the gas absorption and desorption processes. Thus, we report the densities and viscosities of two binary systems: 2-ethoxyethanol (ECS) + water (H2O) and ECS + dimethyl sulfoxide (DMSO), with various compositions at temperatures from (298.15 to 318.15) K. On the basis of these data, excess molar volumes (VmE\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$V_{\text{m}}^{\text{E}}$$\end{document}) and viscosity deviations (Δη) were calculated. The VmE\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$V_{\text{m}}^{\text{E}}$$\end{document} values of the two binary mixtures are negative and decrease with increasing temperatures; Δη values are positive at all compositions and decrease with increasing temperatures.

The physico-chemical properties of the two binary systems, including activation enthalpy and entropy, were calculated from the kinematic viscosity. In addition, various spectral results offer evidence for the formation of weak interactions between ECS and DMSO or H2O.

2-乙氧基乙醇 (1) + 水 (2) 和 + 二甲基亚砜 (2) 二元体系的理化性质和光谱研究

在 CO2 捕获和利用的发展中,二元系统的物理和传输特性很重要,因为它们会影响气体吸收和解吸过程。因此,我们报告了两个二元系统的密度和粘度:2-乙氧基乙醇 (ECS) + 水 (H2O) 和 ECS + 二甲基亚砜 (DMSO),在 (298.15 到 318.15) K 的温度下具有不同的组成。这些数据,多余的摩尔体积(VmE\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek } \setlength{\oddsidemargin}{-69pt} \begin{document}$$V_{\text{m}}^{\text{E}}$$\end{document}) 和粘度偏差 (Δη) 被计算.
