Any other information on results incl. tables

The vapour pressure was measured with the dynamic method in the temperature range of 62 °c to 171 °C. The measured vapour pressures at the corresponding temperatures are listed in the following table:

Temperature/°C Vapour pressure/hPa

62.0                      9.9

80.1                      32.2

92.9                      60.9

104.2                      90.0

108.0                     122.3

123.9                     201.4

133.4                     301.9

143.4                     400.9

150.9                     501.4

157.3                     601.5

162.0                     699.9

171.0                     898.7

The values for 20, 25 and 50 °C are calculated, using the Antoine constants A, Band C as shown.

T/°C       p/ hPa       log (p/hPa) = A + 8/(C+ T[°C])

20       2,4341E-01       A = 5,95716

25       4,2960E-01       B = -842,15       

50       4,2921E+00   C= 108,16
