Solubilities, Densities, Viscosities, Electrical Conductivities, and Refractive Indices of Saturated Solutions of Potassium Sulfate in Water + 1-Propanol at 298.15, 308.15, and 318.15 K

The solubilities, densities, refractive indices, electrical conductivities, and viscosities were determined for saturated solutions of potassium sulfate in aqueous solutions of 1-propanol over the temperature range of 298.15−318.15 K. Different mass fractions of propanol/solution were studied in a range from 0 to 0.6. Equations are given for these properties as a function of temperature and mass fraction of propanol. Knowledge of the properties evaluated and solubility data are useful in the study of the crystallization of potassium sulfate from aqueous solutions by means of the addition of 1-propanol.
