The regression of the vapor pressure data leads with a mean deviation of 0.4% to the following equation:

In ( p/hPa) = 18.4310-3566.78 / (213.01 + t/°C)

The normal boiling temperature was determined at 96.9 °C by extrapolation of the data with this equation.

Remarks

The test item showed fluctuating vapor pressure values - appr. ± 0.4 hPa - at any given temperature. However, these fluctuations were negligible in case of the determination of the normal boiling temperature.
