Liquid-Liquid Equilibria for Geraniol in Aqueous Alcohol Mixtures

Abstract:

Liquid-liquid equilibrium tie-line data were examined for ternary mixtures of (water + methanol + geraniol) and (water + ethanol + geraniol) at 298.15 K. The distribution ratios of alcohol between organic and aqueous phases are discussed. The immiscible area of (water + methanol + geraniol) system is wider than that for the ethanol system. The experimental liquid–liquid equilibrium data have been satisfactorily represented by using an extended UNIQUAC model.
