Abstract

The paper presents experimentally determined (solid + liquid) phase diagrams in the {LiBr (1) + ionic liquid (2) + water (3)} systems. Interpretation of the results and comparison with the literature data for the {LiBr + water} enables the determination of the influence of the ionic liquid on the LiBr solubility in water. It is known that one of the disadvantages of an aqueous lithium bromide solution is the tendency to crystallize, especially with a higher concentration of lithium bromide in the solution. This is one of the problems in absorption refrigeration technology where the aqueous lithium bromide solution is a working fluid commonly used on an industrial scale. One of the possibilities for improving the properties of this system is the use of an additive increasing the solubility of LiBr in water. In this work, the following ionic liquids (ILs): N-(2-hydroxyethyl)ammonium glycolate, N,N-di(2-hydroxyethyl)ammonium glycolate, N,N-di(2-hydroxyethyl)-N-methylammonium glycolate, and N,N,N-tri(2-hydroxyethyl)-ammonium glycolate were considered as an addition to the conventional system. The (solid + liquid) phase diagrams were determined using the dynamic method. Liquid phase range was determined at the absorber operating temperature, T = 303.15 K, and compared to LiBr + water system.

关于{ LiBr (1) + 离子液体 (2) + 水 (3)} 系统（固态 + 液态）相平衡的实验研究

本文介绍了通过实验测定的{锂溴 (1) + 离子液体 (2) + 水 (3)} 系统的（固态 + 液态）相图。通过对结果的解释以及与 {LiBr + 水} 文献数据的比较，可以确定离子液体对 LiBr 在水中溶解度的影响。众所周知，溴化锂水溶液的缺点之一是容易结晶，尤其是当溶液中的溴化锂浓度较高时。这是吸收式制冷技术中的一个问题，而溴化锂水溶液是工业上常用的工作液。改善该系统性能的可能性之一是使用添加剂来增加溴化锂在水中的溶解度。在这项工作中，使用了以下离子液体 (IL)：N-(2-hydroxyethyl)ammonium glycolate、N,N-di(2-hydroxyethyl)ammonium glycolate、N,N-di(2-hydroxyethyl)-N-methylammonium glycolate 和 N,N,N-tri(2-hydroxyethyl)-ammonium glycolate 被视为传统体系的添加剂。采用动态法测定了（固+液）相图。在吸收器工作温度 T = 303.15 K 时确定了液相范围，并与 LiBr + 水系统进行了比较。

期刊介绍： Fluid Phase Equilibria publishes high-quality papers dealing with experimental, theoretical, and applied research related to equilibrium and transport properties of fluids, solids, and interfaces. Subjects of interest include physical/phase and chemical equilibria; equilibrium and nonequilibrium thermophysical properties; fundamental thermodynamic relations; and stability. The systems central to the journal include pure substances and mixtures of organic and inorganic materials, including polymers, biochemicals, and surfactants with sufficient characterization of composition and purity for the results to be reproduced. Alloys are of interest only when thermodynamic studies are included, purely material studies will not be considered. In all cases, authors are expected to provide physical or chemical interpretations of the results. Experimental research can include measurements under all conditions of temperature, pressure, and composition, including critical and supercritical. Measurements are to be associated with systems and conditions of fundamental or applied interest, and may not be only a collection of routine data, such as physical property or solubility measurements at limited pressures and temperatures close to ambient, or surfactant studies focussed strictly on micellisation or micelle structure. Papers reporting common data must be accompanied by new physical insights and/or contemporary or new theory or techniques.
