Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 pressure according to dynamic method (EU method A.4): 11.2 hPa at 20°C
Key value for chemical safety assessment
- Vapour pressure:
- 11.2 hPa
- at the temperature of:
- 20 °C
Additional information
Within the reliable key study (BASF, 2001), the vapour pressure was determined for the test item following EU method A.4 (dynamic method). 12 pressure - temperature pairs had been determined and a vapour pressure curve of excellent linearity was obtained.
The applied interpolation showed a low deviation from measurements (mean deviation: 0.11%) and the estimate for the mean error of measurement was also low (0.5%).
Measurements were performed between 12.9 °C and 124.1 °C. From interpolation, the following result for 20°C was obtained:
Vapour pressure (20°C): 11.2 hPa
This is corroborated by a very similar result from the supporting study (OXEA, 2009): The vapour pressure was determined according to DIN EN 13016 -2, and a value of 15 hPa at 20°C was obtained by extrapolation.
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.
