Liquid−liquid phase equilibria were comparatively studied for the aqueous mixtures of propionic acid with four structurally similar aryl compounds (2-phenylethanol, 1-phenylpropanol, propiophenone, and methyl benzoate) as a function of the mixture composition at T = 298.2 K and p = 0.1 MPa. The cloud point data were measured, and the corresponding solubility diagrams for the studied ternary systems were plotted. Tie lines were measured by the analysis of both the aqueous and organic phases. All of the ternary systems display the type-1 liquid−liquid equilibrium (LLE) behavior. The quality of tie lines was confirmed by the linear behavior of the Othmer−Tobias plot. The thermodynamic model of NRTL was successfully used to correlate the experimental tie lines, and the model binary interaction parameters were determined. Evaluation of the extracting ability of the aryl solvents was performed by the estimation of the solute distribution coefficients and selectivities. Finally, all of the studied aryl solvents are appropriate separating agents for aqueous propionic acid mixtures.

Comparative Evaluation of Liquid–Liquid Phase Equilibria for Aqueous Mixtures of Acetic Acid with Structurally Related Aryl Carbonyl Compounds at 298.2 and 308.2 K

Experimental solubility curves and tie-line compositions were comparatively investigated for the aqueous mixtures of acetic acid with three structurally similar aryl carbonyl compounds (propiophenone, acetophenone, and methyl benzoate) at (298.2 and 308.2) K and 101 kPa. The studied ternary mixtures display type-1 phase behavior. The correlation of the measured tie lines was performed by the NRTL and UNIQUAC models. The model binary interaction parameters were obtained by measured tie-line values and minimizing an objective function. The consistency of the NRTL parameters was validated through topological analysis connected to the Gibbs tangent principle and stability test. Evaluation of the capacity of each solvent was performed using the calculation of distribution coefficients and separation factors. Distribution coefficient (constant) and selectivity (separation factor) values were evaluated over the immiscibility region using the experimental equilibrium data. The influence of extraction temperature on the immiscibility region was found to be minor.
