EXCESS MOLAR VOLUMES AND VAPOR-PRESSURES OF (BENZENE + EACH OF SEVERAL ISOMERS OF BUTANOL)

Excess molar volumes VEm 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 VEms 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 GEm, were calculated by Barker’s method. © 1993 Academic Press Ltd.
