Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The vapour pressure of the substance was determined to be 3.5 E-07 Pa at 20°C and 8.8 E-07 Pa at 25°C.
Key value for chemical safety assessment
- Vapour pressure:
- 0 Pa
- at the temperature of:
- 20 °C
Additional information
Several GLP studies were conducted. They all determined the vapour pressure of the substance to be in the same range.
All studies were conducted in accordance with the OECD Guideline for the Testing of Chemicals 104: "Vapour pressure" by effusion method, weight loss.
The vapour pressure of the pure substance was determined to be 3.5 E-07 Pa at 20°C and 8.8 E-07 Pa at 25°C and in another study 1.0 E-7 hPa at 61.3 °C.
This was supported by an non-GLP study which resltued the vapour pressure for the technical grade of the substance to be less than 1.0 E-5 Pa at 20 °C and 25 °C and by a publication (Walter Gückel, Roland Kästel, Thomas Kröhl & Adolf Parg) where the vapour pressure was determined by evaporation method to be 4.5 E-9 mbar at 20 °C.
The value which originates from the recent study on the pure substance (3.5 E-07 Pa at 20°C and 8.8 E-07 Pa at 25°C) was chosen as key value for the vapour pressure.
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.
