Remarks on result:
other: extrapolated, based on experimental data

Any other information on results incl. tables

Vapour Pressure [hPa]: < 1 * 10E-6 hPa at 20° C, 25° C and 50° C.

The vapour pressures at 20°C, 25°C, 50°C were calculated from the regression equation.

The regression of the results leads with a mean deviation of 8.81 % to the following equation: In(p/hPa) = 14.2482 - 9806.78 I (273.15 + t/°C).
