Abstract: The (vapor + liquid) phase equilibria of (hexane + butan-2-ol) and of (cyclohexane + butan-2-ol) at the temperatures (323.15, 338.15 and 348.15) K have been measured using a Fischer recirculating still. Excess molar Gibbs free energies G E m and activity coefficients were calculated. Thermodynamic consistency was tested. Both mixtures exhibit positive G E m values over the entire composition range in the temperature range studied and an azeotrope exists at all three temperatures. © 1993 Academic Press.
