Experimental solubility curves and tie-line data for the (water + phenol + 1-octanol) system were obtained at T = 298.2 K and atmospheric pressure. The tie-line data were determined bytechniques karl-fischer and refractometry. This ternary system exhibits type-2 behavior of LLE. Distribution coefficients and separation factors were measured to evaluate the extracting abilityof the solvent. The consistency of the experimental tie-line data was determined through theOthmer–Tobias and Bachman equations. The data was correlated with the NRTL (α = ۰٫۲۵) model and the parameters estimated present root mean square deviations below 3%.
