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.

Executive summary:

The vapour pressure test was done according to OECD Guideline 104 using 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.

Vapour pressure at 20.0°C is 9.5 mBar, at 28.6°C is16.5 mBar and at 35.3°C is 19.7 mBar.
