The regression cf the results leads with a mean deviation cf 0.06 % to the following equation:

In(p/hPa) = 16.5594 - 3293.69 I (213.61 + t/°C)

The test item is liquid in the temperature range used for the vapour pressure measurements.

The normal boiling temperature was obtained by extrapolation from the vapour pressure curve.
