Liquid-Liquid Equilibria, and Thermodynamic Properties of the System Methyl Acetate + Methanol + Water at 298.15 K

This paper reports the results of experimental measurements of ternary liquid–liquid equilibria (LLE), densities, and refractive indices of the system methyl acetate + methanol + water, and the binary system methyl acetate + water at 298.15 K, and atmospheric pressure. Values of densities, and refractive indices are measured, and compared by different methods, and mixing rules. Excess molar volumes, and changes of refractive index on mixing were computed from experimental data, a set of empirical equations which are dependent of binary derived contributions being applied. A comparative analysis was performed by application of different group contribution methods to predict experimental LLE behaviour of this ternary mixture.
