Sulfur hexafluoride, thermodynamic properties

FIG. 2-30 Pressure-enthalpy diagram for sulfur hexafluoride (SFe). Properties computed with the NIST REFPROP Database, Version 7.0 (Lemmon, E. W, McLinden, M. O., and Huber, M. L., 2002, NIST Standard Reference Database 23, NIST Reference Fluid Thermodynamic and Transport Properties—REFPROP, Version 7.0, Standard Reference Data Program, National Institute of Standards and Technology), based on the equation of state of de Reuck, K. M., Craven, R.J.B., and Cole, W. A., Report on the Development of an Equation of State for Sulphur Hexafluoride, lUPAC Thermodynamic Tables Project Centre, London, 1991. 

Chemica.1 Properties. With few exceptions, SF is chemically inert at ambient temperature and atmospheric pressure. Thermodynamically SF is unstable and should react with many materials, including water, but these reactions are kineticaHy impeded by the fluorine shielding the sulfur. Sulfur hexafluoride does not react with alkah hydroxides, ammonia, or strong acids.
