Ternary (liquid + liquid) equilibria for β-citronellol in aqueous alcohol at different temperatures

(Liquid + liquid) equilibrium (LLE) data for {water (1) + methanol (2) + β-citronellol (3)} and {water (1) + ethanol (2) + β-citronellol (3)} ternary systems at T = (283.15, 298.15, and 313.15) K are reported. The immiscible region of (water + methanol + β-citronellol) system was found to be larger than that for the ethanol system at the same temperature. The effect of the temperature on the ternary (liquid + liquid) equilibria was examined and discussed. The experimental (liquid + liquid) equilibrium data have been satisfactorily represented by using extended UNIQUAC and modified UNIQUAC models.

► Ternary (liquid + liquid) equilibria containing β-citronellol are reported.
► The influence on temperatures on the systems was examined and discussed.
► The immiscible regions between methanol and ethanol systems were compared.
► The experimental data have been satisfactorily represented by using UNIQUAC models.
