Abstract

Bubble point pressure was measured for a binary, dimethyl ether – 2-butoxyethanol, and a ternary, dimethyl ether – water – 2-butoxyethanol, by use of a static apparatus with a glass cell up to 837.0 kPa at (293.15 to 313.15) K. The mole ratios of water: 2-butoxyethanol were set to 50.0:50.0, 90.0: 10.0 and 95.0: 5.0 in the liquid phase for the ternaries. The phase behavior was visually observed through the glass cell at the pressure measurements, because the vapor-liquid-liquid equilibria (VLLE) have been reported for dimethyl ether -water. The binary showed the vapor-liquid equilibrium (VLE), which almost followed an ideal solution. 2-Butoxyethanol enhanced the miscibility range for dimethyl ether – water. Only the VLE was observed in the two ternaries with water: 2-butoxyethanol = 50.0: 50.0 and 90.0:10.0. The VLLE was partly observed in the ternary with water: 2-butoxyethanol = 95.0: 5.0. The NRTL equation was employed to correlate the VLE and the VLLE not only for dimethyl ether – 2-butoxyethanol but also for the other constituent binaries, dimethyl ether - water and water – 2-butoxyethanol. The NRTL equation provided good reproducibilities for dimethyl ether - 2-butoxyethanol with the average value of the absolute relative deviations (AARDs) of 0.90 % for the pressure. Using the parameters fitted with the constituent three binary data, the AARDs were 5.04 %, 6.80 % and 12.21 % for the pressure of dimethyl ether – water – 2-butoxyethanol with water: 2-butoxyethanol = 50.0: 50.0, 90.0: 10.0 and 95.0: 5.0, respectively. The experimental data and the prediction will contribute to design the sprays using water-based solvents for color paints, disinfectants, cleaning agents, cosmetics, pharmaceuticals and so on.

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.
