New solubility and liquid-liquid equilibrium (LLE) data of solutions of (water + ethanol + alpha,alpha,alpha-trifluorotoluene) are determined at three temperatures (288.15, 298.15, and 308.15) K and atmospheric pressure. The solubility and LLE data are correlated quantitatively by empirical equations, NRTL, and UNIQUAC models. The effect of temperature upon miscibility of the ternary systems is small. Practically, alpha,alpha,alpha-trifluorotoluene is capable to extract efficiently ethanol from its dilute aqueous solutions to obtain absolute alcohol. (c) 2006 Elsevier Ltd. All rights reserved.
