Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 auto-ignition temperature of the high trans (cis/trans:10:90) quality is 259°C. Cis quality is expected to be similar.
No additional flammability hazard is therefore expected in normal conditions of storage and use.

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:
259 °C

Additional information

The auto-ignition temperature on the high trans quality (cis/trans: 10:90) of the substance was determined according to the DIN 51794 standard. The result was found to be 259°C. No data is available for the high cis quality, however no significant difference is expected from the similar boiling points and flash points.
