The vapour pressure was determined by a static method.

Few grams of material were placed in a 50 ml glass bottle.

Glass bottle thermostated and system evacuated with a vacuum pump for 5 minutes.

Pressure measured with a pressure transmitter, Yokogawa no 918609418. Measuring up to 130 mBar.

Results at 20.0°C 9.5 mBar

28.6°C 16.5 mBar

35.3°C 19.7 mBar.

Conclusions:
Vapour pressure at
20.0°C: 9.5 mBar
28.6°C: 16.5 mBar
35.3°C: 19.7 mBar.
