N2 - The cohesive energy densities ced and the internal pressures Pint of aqueous acetone mixtures are calculated from literature data for the entire composition range at 298.15 K at saturation pressures. The ratios Pint/ced are measures of the ‘structuredness’ of the studied fluids, the small values noted signify ‘tight’ structures, due to the hydrogen bonding. The ‘tighter’ the structure, the larger is the surface tension of the mixtures. This structural feature diminishes in intensity as the temperature and the acetone contents are increased.
