ABSTRACT
Liquid-liquid equilibria (LLE) for the ternary system water + 1-butanol + 2-ethyl-1-hexanol at (298.2, 303.2, 308.2, and 313.2) K are reported. A type-2 liquid-liquid phase diagram was obtained for this ternary system. The UNIQUAC model was used to correlate the LLE data with a root-mean-square deviation value of 1.08%. The UNIQUAC interaction parameters between each pair of components in the system were obtained using the experimental results. The effect of 1-butanol addition on mutual solubility of 2-ethyl-1-hexanol and water was also investigated at different temperatures.
