ABSTRACT
The solubility of sulfuryl fluoride in water was experimentally measured over the pressure from P = (0 to 600) kPa and T = (283.15 to 308.15) K using isochoric saturation method. Results show that SO2F2 solubility increases with increasing pressure and decreases with increasing temperature. Using the experimental solubility data, Henry s law constants and the thermodynamic properties such as the standard Gibbs free energy, enthalpy, and entropy changes of SO2F2 solvation were obtained. Henry s law constant based on mole fraction and molality of SO2F2 in water vary from (432.21 to 1052.96) MPa and (7.78 to 18.96) MPa at T = (283.15 to 308.15) K, respectively.
