ABSTRACT
Liquid liquid equilibria (LLE) data for the water + cyclohexanone + solvents (toluene or p-xylene) ternary systems were reported at 303.15 and 323.15 K under 101.3 kPa. The distribution coefficient (D) and separation factors (S) were calculated to evaluate the separating efficiency of the selected solvents. Besides, both the Hand and the Bachman correlation equations were used to ascertain the reliability and consistency of the obtained LLE data. The nonrandom two-liquid (NRTL) and the universal quasi-chemical activity coefficient (UNIQUAC) models were both applied to correlate the experimental results for the studied ternary systems with the RMSD% values of these two models as low as 0.16. Also, the binary interaction parameters were obtained for these two correlation models.
