Kirkwood−Buff Integrals in Aqueous Alcohol Systems: Comparison between Thermodynamic Calculations and X-Ray Scattering Experiments

摘要: Thermodynamic data were used to calculate the Kirkwood−Buff integrals for aqueous solutions of methanol, ethanol, propanols, and butanols. The calculated values have been compared those obtained from small-angle X-ray scattering (SAXS) experiments, satisfactory agreement was found. Improved expressions suggested excess number molecules around central ones. On this basis, information about structure gathered, main conclusion being that interactions among similar prevail; leads clustering dominated by same kind molecules.
