Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

- Key result
- Remarks on result:
- other: No autoignition tempererature have been measured at 6 bar up to 500°C
- Conclusions:
- The autoignition temperature of the test substance is higher than 500°C at 6 bar.
- Executive summary:
The autoignition of the test substance was performed according to a method which meets generally accepted scientific principles and was well documented.
The test substance was put into a heated flask (100°C), then the temperature of the flask is increased. Pressure and temperature of the flask were measured. A sudden increase of these two parameters is the criterion for autoignition of the test substance.
The autoignition temperature of the test substance is higher than 500°C at 6 bar.
Reference
The criterion for autoignition was sudden temperature and pressure increase.
During the screening test up to 500°C a sudden decomposition was not observed. At temperatures of more than 450°C a moderate pressure decrease was found. Maybe, this is caused by a slow decomposition or cracking reaction.
Additionnal test were performed at a maximum temperature of 500°C, no autoignition reaction was observed. So the autoignition at 6 bar is above 500°C.
Description of key information
The autoignition of the test substance was performed according to a method which meets generally accepted scientific principles and was well documented.
The autoignition temperature of the test substance is higher than 500°C at 6 bar.
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 500 °C
Additional information
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.
