Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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.
