Vapor-liquid equilibrium at 101.3 kPa has been determined for the ternary system 2-chlorobutane + 1-chlorobutane + cyclohexane and its binaries 2-chlorobutane + cyclohexane and 1-chlorobutane + cyclohexane. The binary system 1-chlorobutane + cyclohexane presents an azeotropic point at 76.86 C that contains 57.5%mol 1-chlorobutane. No ternary azeotrope is present. The data were correlated by the Redlich-Kister, Van Laar, Wilson and Wisniak-Tamir equations and the appropriate parameters are reported. The activity coefficients of the ternary system can be predicted from those of the pertinent binary systems.
