The regression of the vapor pressure data leads with a mean deviation of 0.96 % to the following rounded equation:

In ( p/hPa) = 21.2438 -5395.89 / ( 273.15 + t/°C)

With this equation, the values of the following table were calculated:

c) interpolated

d) extrapolated

Remarks

At a temperature of approximately 60°C and above a continuously increasing vapor pressure was observed. This indicates a thermally caused change of the test item.
