Liquid–Liquid Phase Behaviors of Geraniol in Aqueous Alcohol Mixtures

Liquid–liquid equilibrium (LLE) data of the binodal curves and tie-line compositions were examined for ternary mixtures of (water + methanol + geraniol) and (water + ethanol + geraniol) at T = (283.15, 298.15, and 313.15) K. The immiscible area of the (water + methanol + geraniol) system is wider than that for the ethanol system at the same temperature. The experimental liquid–liquid equilibrium data have been represented by using the original UNIQUAC, extended UNIQUAC, and modified UNIQUAC models.
