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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Vapour pressures from seven references: 0.065 mBar at 20 degrees C, 0.8 mBar at 50 degrees C, 0.06 mBar (given as 0.045 mmHg) at 20 degrees C, 0.096 mBar (given as 0.072 mmHg) at 25 degrees C, 0.065 mBar at 20 degrees C, between 0.048 and 0.067 mBar at 20 degrees C, 0.053 mBar at 20 degrees C, 0.8 mBar at 50 degrees C, 0.06 mBar at 20 degrees C, 0.04 mBar at 20 degrees C, 0.065 mBar at 20 degrees C, 1.7 mBar (given as 1.3 mmHg) at 60 degrees C, and 0.067 mBar (given as 0.05 mmHg) at 20 degrees C.
Key value for chemical safety assessment
- Vapour pressure:
- 6 Pa
- at the temperature of:
- 20 °C
Additional information
There was a range of vapour pressures reported at 20 degrees C, from 0.04 - 0.67 mBar. The median value corresponded with the experimental value reported from Clayton and Calyton 1982, 0.06 mBar at 20 degrees C. This was chosen as the key value, and was converted to the units of pascals using 1 millibar = 100 pascal.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
