Vapor-liquid equilibrium at 94.4 kPa has been determined for the ternary system hexane + 1-chlorobutane + 2-propanol and the binary systems hexane + 1-chlorobutane and 1-chlorobutane + 2-propanol. The binary system hexane + 1-chlorobutane exhibits moderate deviations from ideality and an azeotrope that contains 97.5 mol % hexane and boils at 339.25 K. The binary system 1-chlorobutane + 2-propanol presents strong deviations from ideality and an azeotrope that contains 62.8 mol % 1-chlorobutane and boils at 341.60 K. The equilibrium data were correlated by the Redlich-Kister, Wilson, UNIQUAC, UNIFAC, and Wisniak-Tamir equations, and the appropriate parameters are reported. The activity coefficients of the ternary system are predicted from those of the pertinent binary systems very well by the Wilson equation and not so well by the Redlich-Kister equation. A ternary azeotrope is not present.
