Abstract

Densities of the following pure ionic liquids: 1,3-dimethyl-imidazolium dimethyl phosphate, [C₁C₁IM][DMP], 1-ethyl-3-methylimidazolium diethyl phosphate, [C₁C₂IM][DEP], 4-ethyl-4-methylmorpholinium dimethyl phosphate, [C₁C₂MOR][DMP], 4-ethyl-4-methylmorpholinium diethyl phosphate, [C₁C₂MOR][DEP], 1-ethyl-1-methylpyrrolidinium diethyl phosphate, [C₁C₂PYR][DEP], 1-(2-hydroxyethyl)-1-methylpyrrolidinium dimethyl phosphate, [C₁C_2OHPYR][DMP] and 1-ethyl-1-methylpiperidinium dimethyl phosphate, [C₁C₂PIP][DMP] have been determined using a vibrating tube densimeter. Measurements have been done over the temperature range from T = (298.15 to 348.15) K and pressure p = (0.1 to 40) MPa. The densities at ambient and high pressures are measured to present the physicochemical properties of the ILs proposed as an absorbent in absorption refrigeration technology. The Tait equation with the temperature-dependent parameters has been used to correlate the experimental density values. The correlation equation has been used to compute isothermal compressibilities (α) and isobaric expansivities (κ).

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.
