Results and discussion

Vapour pressure
Temp.:
115.2 °C
Vapour pressure:
0.2 hPa

Any other information on results incl. tables

temperature (°C)        vapour pressure (hPa)
115.2 0.20
121.7 0.30
135.9 0.70
142.5 1.00
155.3 2.00
162.8 3.00
173.3 5.00
180.6 7.00
188.7 10.00

At temperatures higher than 200 °C occur high change of
temperature. This point to a possible decomposition of
substance.
