The regression of the results leads with a mean deviation of 0.16 % to the following equation:
ln(p/hPa) = 10.1567 - 4386.04 / (188.33 + t/°C)
The vapour pressure at 20 °C, 25 °C and 50°C was calculated from the regression equation.
The normal boiling temperature was obtained by extrapolation from the vapour pressure curve.
