Model for Boiling Point

ln(p/) = a1 + a2/T + a3×ln(T) + a4×T + a5×T2 + a6/T2 + a7×T6 + a8/T4

where = 1 kPa

The basis for this functional form is discussed in [1].

Please note that the equations described above are expressed in terms of vapor pressure and not in the necessary inverted form. The parameters for a given fit can be found in the model summary for the associated phase boundary pressure contour.
