Vapor-liquid equilibria (VLE) data of 2-butanol + benzene or toluene or o- or m- or p-xylene measured by static method at 308.15 ± 0.01 K over the entire composition range are reported. The excess molar Gibbs free energies of mixing (GF) for these binary systems have been calculated from total vapor pressure data using Barker's method. The GE for these binary systems are also analyzed in terms of the Mecke Kempter type of association model with a Flory contribution term using two interaction parameters and it has been found that this model describes well the GE values of binary systems benzene or toluene.
