The regression of the results leads with a
mean deviation of 0.16 % to the following equation:
ln(p/hPa) = 9.9933 - 4419.00 / (152.74 + t/°C)
The vapour pressure at 20 °C and 25 °C was
calculated from the regression equation.
The normal boiling temperature was obtained by extrapolation from the
vapour pressure curve.
