Abstract

Vapour pressures of butyl acetate + benzene or toluene or o- or m- or p-xylene were measured by static method at 298.15 ± 0.01 K over the entire composition range. The activity coefficients and excess molar Gibb's free energies of mixing (GE) for these binary mixtures were calculated by fitting vapour pressure data to the Redlich-Kister equation using Barker's method of minimizing the residual pressure. The GE values for the binary mixtures containing benzene are positive; while these are negative for toluene, ortho, meta and para xylene system over the whole composition range. The GE values of an equimolar mixture for these systems vary in the order: benzene > m-xylene > o-xylene > p-xylene > toluene.
