Résumé : The present work exposes a thermodynamic framework of the modeling of the vapor liquidequilibrium for the three binary systems composed of methanol-water, methanol-ethanol and ethanol-cyclohexane at 101.3 kPa. The experimental data were correlated using the extended UNIQUAC model. The deviations between the calculated and experimental vapor-phase compositions, liquid-phase compositions and bubble point temperatures have been determined. To improve the accuracy of the proposed model we determine the deviations between the calculated and experimental values with respect to all variables (i.e.vapor-phase compositions, liquid-phase compositions and bubble point temperatures). The calculated results of methanol-water,, methanol-ethanol and ethanol-cyclohexane mixtures are compared with experimental data presented in literature showing minimum of deviations.
