(Liquid + liquid) equilibrium for ternary system of (water + phenol + cyclohexanone) at T=۲۹۸.۲ K

Experimental solubility curves and tie-line data for the (water + phenol + cyclohexanone) system was obtained at T = ۲۹۸.۲ K and atmospheric pressure. The tie-line data was determined by techniques karl-fischer and refractometry. This ternary system exhibits type-۲ behavior of LLE. Distribution coefficients and separation factors were measured to evaluate the extracting ability of the solvent. The consistency of the experimental tie-line data was determined through the Othmer–Tobias and Bachman equations. The data were correlated with the NRTL (Į = ۰.۲۵) and UNIQUAC models and the parameters estimated present root mean square deviations below ۲%.
