| Abstract: | Numerous sets of vapor pressure-composition data for methanol in dilute aqueous solutions at 25°C and 35°C have been obtained with an automated vapor pressure apparatus developed in this laboratory. Activity coefficients of both components and values of the pairwise free energy of interaction of methanol molecules have been inferred from the results. The osmotic second virial coefficient of methanol has also been calculated and compared with literature values of this quantity. |
