Tie Line

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

Tie Line

Isobaric liquid-liquid equilibrium tie-line data were determined at atmospheric pressure and at 283.15 and 313.15 K for the mixture (water + methanol +citral). The miscibility for the ternary (water + methanol + citral) LLE was increasing as the temperature increased. The experimental liquid–liquid equilibrium data have been satisfactorily represented by using an extended UNIQUAC model.
