ABSTRACT
Liquid-liquid equilibrium (LLE) data were measured for the ternary mixtures of water + ethanol + 1-hexanol, water + ethanol + butyl propionate, and water + ethanol + ethyl caproate at atmospheric pressure over a temperature range of 283.15 K to 323.15 K. All three ternary systems exhibit type I behavior of LLE. The area of the two-phase region decreases with increasing temperature for each ternary system; its magnitude follows the order of the mixtures containing ethyl caproate > butyl propionate > 1-hexanol. The NRTL and the UNIQUAC models correlated the LLE data very well, except for the region near the plait point. The NRTL model is generally better than the UNIQUAC model for representing the LLE behavior for the three investigated systems.
