Liquid–liquid equilibrium (LLE) data of water + butyric acid + {butanal or n-butanol} ternary systems were determined at T = 293.15, 308.15, and 323.15 K and p = 0.1 MPa. The ternary systems investigated display Type I behavior of LLE. Nonrandom two-liquid (NRTL) and universal quasichemical (UNIQUAC) activity coefficient models were applied here to fit the experimental results, and the root-mean-square deviations (RMSD) between experimental data and calculated ones were considered in the calculation. The results indicated that the LLE data were well-fitted with both models, in which the RMSD were less than 0.0124. Moreover, solute and diluent compositions in each equilibrium phase were used to calculate the distribution coefficient (D) and the selectivity (S).

“…Experimental values of density, speed of sound, and refractive indices of the pure chemicals are listed in Table along with literature data − for comparison, and our experimental values show good agreement with the literature data. The non-notable deviations between our data and literature data may have resulted from human experimental error, experimental techniques and/instruments used, impurities in pure chemicals including water content as well as handling, preparation of the samples, and so forth.…”

Measurements and Modeling of Physicochemical Properties of Pure and Binary Mixtures Containing 1,2-Dimethoxyethane and Some Alcohols

et al. 2021

In this paper, experimental values of densities, speeds of sound, and refractive indices in a temperature range of 293.15−323.15 K have been measured as a function of composition for the binary liquid mixtures of 1,2dimethoxyethane with alcohols such as methanol, propan-1-ol, propan-2-ol, and butan-2-ol. From these experimental values, excess/derived properties such as excess molar volume, isentropic compressibility, deviation in isentropic compressibility, and deviation in the refractive index have been calculated. Excess/derived properties have been correlated using the Redlich− Kister equation and physicochemical properties modeled using the cubic plus association equation of state for pure and binary mixtures. The results are interpreted with respect to possible molecular interactions between components.

“…This was accomplished by utilizing the Karl Fisher coulometer (756KF Coulometer Metrohm). Experimental values of density, speed of sound, and refractive index of the pure liquids are compared in Table at (293.15, 298.15, 303.15, 313.15, and 323.15) K, and these values show good agreement with the published results. ,− …”

Thermodynamic, Ultrasonic, and Transport Study of Binary Mixtures Containing 2-(2-Methoxyethoxy)ethanol and Alcohols at (293.15–323.15) K

et al. 2020

Binary mixtures of 2-(2-methoxyethoxy)ethanol and alcohols were characterized in terms of the existence of intermolecular interactions at different temperatures (293.15, 303.15, 313.15, and 323.15) K and at pressure p = 0.1 MPa. The alcohols were methanol, ethanol, propan-1-ol, propan-2-ol, butan-1-ol, and butan-2-ol. The study was based on the measurements of densities, speeds of sound, and refractive indices over the entire range of mixture compositions. The obtained data were used to calculate various thermodynamics/ deviation properties: excess molar volume, isentropic compressibility, deviation in isentropic compressibility, and deviation in refractive indices. Excess/deviation properties were fitted to the Redlich−Kister equation to estimate the coefficients. The standard deviation of the fit was calculated between the predicted and the experimental quantities to ensure the accuracy of the experimental data.
