Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
1.263 Pa at 20 °C.
Key value for chemical safety assessment
- Vapour pressure:
- 1.263 Pa
- at the temperature of:
- 20 °C
Additional information
A study was conducted to determine the vapour pressure. Using the dynamic method the vapour pressure was determined in 8 measurements in a temperature range from 71 to 163 °C. Using the Ebulliometric determination method the correlation constants were determined and the vapour pressure at 20 °C was calculated to be 0.012629 mBar. In addition the GESTIS database reports the vapour pressure at 20 °C to be 0.05 mBar. Thus, as the vapour pressure values were close to each other, the calculate value was regarded as reliable and was chosen as key parameter.
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.
