(liquid + liquid) equilibrium experiment and thermodynamic modeling of water + o-cresol + solvents (Mesityl oxide or n-Propyl acetate) at 303.2, 313.2, and 323.2 K under 101.3 kPa

Abstract

In this work, the liquid-liquid equilibrium (LLE) data of the ternary mixtures of water + o-cresol + solvents (mesityl oxide or n-propyl acetate) were measured at 303.2, 313.2, and 323.2 K under 101.3 kPa. The distribution coefficients (D) and separation factors (S) were used to evaluate the effect of extracting o-Cresol from water and the high D and S values indicated that the two solvents are promising. At the same time, the NRTL and UNIQUAC models were used to correlate experimental data, and obtain regression parameters with the root mean square (RMSD) values less than 0.50%. In addition, the GUI-MATLAB tool was used to verify the good reliability of the regression parameters.
