摘要：

Isothermal vapor-liquid equilibria (VLE) for mixtures containing 2-propanol + tetrahydrofuran + 1-chlorobutane have been measured using a modified version of a Boublik-Benson still at 25degreesC. A test of thermodynamic consistency, like the McDermott-Ellis method was applied to the activity coefficients Excess molar Gibbs free energies were calculated over the entire range composition. Different expressions existing in the literature were used to predict activity coefficients.
