(Vapour + liquid) equilibria (VLE) data of (1-butanol + benzene, or toluene, or o-, or m-, or p-xylene) measured by the static method at T = (308. 15 ± 0.01) K over the entire composition range are reported. The excess molar Gibbs free energies of mixing GmE for these binary systems have been calculated from total vapour pressure data using Barker's method. The GmE 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 GmE values of these binary systems.
