Liquid-liquid equilibrium data for the (water + 2-butanol + 2-ethyl-1-hexanol) ternary system were
determined at T = (298.2, and 308.2) K in atmospheric pressure. 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 raw experimental data were correlated
using NRTL model. The results are very satisfactory, with root mean square deviations below
0.8% between experimental and calculated equilibrium mass fractions.
