Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Vapor Pressure: 3.44 Pa at 25 °C, EU Method A.4, Harlan Laboratories Ltd. 2013
Key value for chemical safety assessment
- Vapour pressure:
- 3.44 Pa
- at the temperature of:
- 25 °C
Additional information
The vapour pressure was determined using EU Method A.4 using the gas saturation method. To ensure saturation control, three different flow rates were used at each temperature. In the determination higher flow rates did not lead to lower vapor pressures, which means that the nitrogen was saturated with substance under the conditions of the test. The mean vapor pressure was 30°C: 5.36 Pa ; 40°C: 11.9 Pa and 50°C: 26.6 Pa respectively. The vapor pressure of the substance was extrapolated from the vapor pressure curve (ln Pvp versus 1/T) and was calculated to be 3.44 Pa.
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.
