Liquid + Liquid Equilibrium for Ternary System of Water + Phenol + Cyclohexane at T = 298.2 K

Experimental solubility curves and tie-line data for the water + phenol + 2-ethyl-1-hexanol system was obtained at T = 298.2 K and atmospheric pressure. The tie-line data was determined by techniques karl-fischer and refractometry. This ternary system exhibits type-2 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 a = 0.25 and UNIQUAC models and the parameters estimated present root mean square deviations below 0.50%.
