The experimental study on the (solid + liquid) phase Equilibria for {LiBr (1) + ionic liquid (2) + water (3)} systems
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.
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.
