The vapor-liquid equilibrium (VLE = pressure, temperature, and composition of coexisting vapor and liquid phases) was measured at 313.15, 323.15, and 333.15 K by the ebulliometric method for the binary systems formed by allyl alcohol with benzene and with cyclohexane. Positive azeotropes were found in both systems. The experimental VLE results were correlated with equations representing liquid-phase activity coefficients and by the AEOS (association + equation of state) equation of state.
