Vapor pressure


  • Values are given in terms of temperature necessary to reach the specified pressure.
  • Valid results within the quoted ranges from most equations are included in the table for comparison.
  • A conversion factor is included into the original first coefficients of the equations to provide the pressure in pascals (CR2: 5.006, SMI: -0.875).
  • Ref. SMI uses temperature scale ITS-48. No conversion was done, which should be of little consequence however.
  • The temperature at standard pressure should be equal to the normal boiling point, but due to the considerable spread does not necessarily have to match values reported elsewhere.

Uncertainties of several degrees should generally be assumed. (e) Indicates extrapolated values beyond the region of experimental data, subject to greater uncertainty. (i) Indicates values calculated from ideal gas thermodynamic functions. (s) Indicates the substance is solid at this temperature. As quoted from these sources:
