Binodal and tie line points (LLE) for the 2,2,2-trifluoroethanol + ethanol + cyclohexane system were determined at the temperatures T = (288.15, 298.15, and 308.15) K and atmospheric pressure. Consistent liquid-liquid equilibrium data and plait points were attained using Hand, Othmer-Tobias, NRTL, and UNIQUAC equations. The strength of the binary intermolecular interaction governing the unlike molecules was evaluated. For alcohol-rich solutions, molecular cluster formation by a variety of hydrogen-bonding configurations between ethanol and trifluoroethanol hydroxyl groups and fluorine atoms results in a moderate temperature effect on the phase behavior of the partially miscible system.
