Abstract
- The solubilities of sulfuryl fluoride (SO 2 F 2 ) in propylene carbonate (PC), tributyl phosphate (TBP) and N-methylpyrrolidone (NMP) was measured by isochoric saturation method at the pressure of up to 600 kPa and temperatures ranging from (293.15 to 313.15) K. Results showed that SO 2 F 2 solubility increased with increasing pressure and decreased with increasing temperature in the three solvents, and the dissolution of SO 2 F 2 in the solvents was a physical process. Moreover, Henry’s law constants and thermodynamic properties such as standard Gibbs free energy, enthalpy, and entropy changes of SO 2 F 2 solvation were further calculated according to the experimental solubility data. The solubility of SO 2 F 2 in these three solvents followed the order of TBP > PC > NMP. The results illustrated that TBP possessed the potentiality to capture SO 2 F 2 among the present absorbents due to the relatively large solubility and low absorption enthalpy for SO 2 F 2 .
