Excess molar volumes and vapour pressures of (benzene + each of several isomers of butanol)

Abstract

Excess molar volumes V E m of (benzene + each of several isomers of butanol) have been obtained at the temperature 298.15 K over the whole range of mole fractions from densities measured with a vibrating-tube densimeter. All the V E ms were positive. Vapour pressures of the same mixtures at the same temperature were measured by a static method. Composition of vapour, along with the activity coefficients and excess molar Gibbs free energies G E m, were calculated by Barker's method.
