Isobaric vapor-liquid equilibrium data for the systems ethanol + 1,2-ethanediol, ethanol + methyl benzoate, 2-propanol + 1,2-ethanediol, 2-propanol + methyl benzoate and ethanol + 2-propanol were measured at atmospheric pressure (0.1013 MPa) with a CP-I dual circulation vapor-liquid equilibrium still. The results of the correlation of the experimental data with three thermodynamic models, DORDF, UNIQUAC and NRTL, were compared.
