Thermodynamic properties of neat ethanol and water over a wide temperature range, from below ambient to supercritical conditions obtained from the literature are summarized for use in the evaluation of the preferential solvation that takes place in aqueous ethanol mixtures. Preferential solvation parameters, describing the composition of the near environments of molecules of the two components in the mixtures, were calculated, using the inverse Kirkwood-Buff integrals theory. The extent of hydrogen bonding in pure ethanol and its aqueous mixtures was evaluated from infrared and NMR spectroscopic data in the literature. These data were compared with those of aqueous methanol mixtures previously studied by the author.
