This paper deals with the physico-chemical properties of ethanol and ethanol-water solutions. The data of ethanol properties and its water solutions, which were obtained from literature, are presented in the form of Equations and Tables.Extended properties include data for pure ethanol (density, vapor pressure, surface tension, viscosity, molar and specific heat capacity, enthalpy of evaporation, thermal conductivity and static relative permittivity) and tabled data for ethanol-water solutions (0–100% ethanol) as well: concentrative properties, surface tension and thermal conductivity at20 °C, density, viscosity, boiling point and equilibrium liquid-vapor at normal pressure.

Vapor Pressure Measurements

The vapor pressures of solutions of sodium chlorate and of lithium chlorate in water and in solvents consisting of 44.5% dioxane–55.5% water and of 64.5% dioxane–35.5% water, at 25 °C, were determined using a differential manometer. The vapor compositions of the dioxane–water solutions were found by the air-saturation method.The mean molal activity coefficients were calculated from the vapor pressures and compositions. The activity coefficients of the solute were fitted to the theoretical equations of Stokes and Robinson and of Glueckauf, yielding hydration numbers for the cations of the salts.The minimum dioxanation numbers of sodium and of lithium chlorates in the dioxane–water mixtures were calculated from the experimental activity coefficients by the method of Grunwald. The results show that lithium chlorate is more highly solvated than sodium chlorate and that dioxane plays a major role in the solvation of both electrolytes in the dioxane–water mixtures.
