Ternary (liquid + liquid) equilibrium experiment and thermodynamic modeling for water + cyclohexanone + mesityl oxide at 298.2, 303.2 and 313.2 K under 101.3 kPa

To separate and purify cyclohexanone from water, in 101.3 kPa, 298.2, 303.2 and 313.2 K, the liquid–liquid equilibrium (LLE) data of the ternary mixture of water + cyclohexanone (CYC) + mesityl oxide were presented. The distribution coefficient (D) and separation factor (S) appraised the utility of extracting cyclohexanone from water. The NRTL and UNIQUAC models successfully correlated the experimental data with RMSD less than 0.29%. The GUI-MATLAB tool was used to verify the good reliability of the regression parameters.
