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 (G^E) 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 G^E 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 G^E values of an equimolar mixture for these systems vary in the order: benzene > m-xylene > o-xylene > p-xylene > toluene.
