Description of key information
Vapour pressure at 20°°C: 2.4E-7 hPa
Key value for chemical safety assessment
- Vapour pressure:
- 0 hPa
- at the temperature of:
- 20 °C
Additional information
The DSC-measurement in a closed glass crucible showed various exothermic effects in the temperature range of 95°C – 150°C and in the temperature range of 240°C – 310°C and an endothermic effect in the temperature range 205°C -240°C.
Vapour Pressure Balance (Effusion Method)
The vapour pressure was measured in the temperature range of 30°C to 123°C. Above 66°C a vapour pressure could be measured.

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.
