New vapor-liquid equilibrium data have been obtained for the binary system hexane + 2-propanol at 94.4 kPa to compare with previously reported data assumed to be thermodynamically inconsistent. The system exhibits large positive deviations from ideal behavior and an azeotrope that boils at 332.92 K and contains 73.3 mol % hexane. The activity coefficients and boiling point of the solution were correlated with its composition by the Redlich-Kister, Wilson, UNIFAC, UNIQUAC, and Wisniak-Tamir models.
