Vapor–Liquid Equilibria, Density, Sound Velocity, and Refractive Index for Binary Mixtures Containing 2-(2-Ethoxyethoxy)ethanol and 1-Propanol or 2-Propanol or 1-Butanol or 2-Butanol at Different Temperatures

In this work, we have reported the vapor liquid equilibria (VLE) data for the binary mixtures containing {2-(2-ethoxyethoxy)ethanol (1) + 1-propanol, 2-propanol, 1-butanol, or 2-butanol (2)}. All the VLE measurements were conducted at temperatures ranging between (273.15 to 363.15) K over the whole composition range. The NRTL and UNIQUAC models were used to correlate the VLE experimental data. Furthermore, experimental measurements of densities, sound velocities, and refractive indices were measured for aforementioned binary mixtures at atmospheric pressure and at T = (293.15, 303.15, 313.15, and 323.15) K. By utilizing the experimental results, the excess/deviation functions were calculated and fitted to the Redlich−Kister polynomial equation.

Experimental High-Temperature, High-Pressure Density Measurement and Perturbed-Chain Statistical Associating Fluid Theory Modeling of Dimethyl Sulfoxide, Isoamyl Acetate, and Benzyl Alcohol

Experimental high-temperature, high-pressure (HTHP) density of three solvents including dimethyl sulfoxide, benzyl alcohol, and isoamyl acetate was measured at temperatures of 293.15–473.15 K and pressures up to 35–37.5 MPa. The density was measured with an Anton Paar density meter (DMA HP) at 20 K and 2.5 MPa intervals. The calibration fluids were water and benzene. The combined expanded uncertainty of density taking into account the device specification and the impurities of the materials was 1 kg·m–3 (0.95 level of confidence). The experimental density data were correlated with the Tait and new modified Tait equations. The thermal expansion coefficient (α p ) and isothermal compressibility (κ T ) were calculated with the new modified Tait equations. Moreover, the perturbed-chain statistical associating fluid theory (PC-SAFT) equation of state was used to model the density data at HTHP. In most cases, the PC-SAFT parameters are obtained from saturated vapor pressure and liquid phase density; however, these parameters were calculated from the density at HTHP in the present study. Regarding these parameters, thermodynamic properties such as the thermal expansion coefficient (α p ), isothermal compressibility (κ T ), isobaric heat capacity (C P ), and speed of sound (u) were calculated. Acceptable agreement between the results with experimental data demonstrated the accuracy of modeling with the obtained parameters.

Thermophysical Property Measurements and Modeling of (Ether + Alkanol + Hydrocarbon) Mixtures: Binary and Ternary Mixtures (Dibutyl Ether + 1-Butanol + 1-Hexene or + Iso-octane) at 298.15 K

Herein, the speed of sound (u), refractive index (n D ), and density (ρ) for the present ternary blends, dibutyl ether (1) + 1-butanol (2) + 1-hexene (3) and dibutyl ether (1) + 1-butanol (2) + iso-octane (3), and their corresponding binary blends are measured (549 points) at 0.1 MPa and at 298.15 K. Based on the data collected, the deviations in the speed of sound (Δu), the deviations in the refractive index (Δn D ), the excess volume (V E ), the isentropic compressibility (k s ), and the deviations in isentropic compressibility (Δk s ) are calculated and correlated to the Redlich−Kister (RK) equation of state (EoS). Besides, the perturbed-chain statistical associating fluid theory (PC-SAFT) EoS is used to model the reported data of ρ, and a high accordance is found between the measured and modeled data of ρ for diverse mixtures examined in this study.
