Investigation of liquid – liquid equilibria for ternary systems using different thermodynamical models

(Liquid + liquid) equilibrium data are presented for (water + acetic acid + 1-hexanol), (water + formic acid + 1-octanol) at T = 293.15 K and atmospheric pressure. Phase diagrams were obtained by determining tie-line data. The NRTL, UNIQUAC, UNIFAC and Dortmund – Modified UNIFAC models were used in order to calculate the phase compositions of the ternary systems, and results were compared with experimental data.
