Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Self-ignition temperature: 244°C at 1013 hPa
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 517 K
Additional information
Several measured self-igntion temperatures are available. Those known to have been conducted according to international or national standard methods are considered reliable, even though little further information about the studies is available. Three studies gave values in the range 235 - 260°C; one study gave a value of 316°C. Variations in the self-ignition temperature values may be caused by variations in purity of the test substance and in the test method used, although it is not clear why such a large variation is observed between the lower and upper values. The values in the range 235 -260°C are considered to represent a worst-case. Therefore, the key study is selected from among these values because it is the only one of them with a purity value (99%) given.
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.
