Executive summary:

Chemical Engineering (1972) is company data with no details on methods used or test conditions. The data is non-GLP, guideline study, and has been considered reliable with restriction as there is limited information provided for method.

Description of key information

The autoflammability of the Hydrocarbons, C9, aromatics is > 400°C at 1 atm. 

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:
400 °C

Additional information

The autoflammability of the Hydrocarbons, C9, aromatics was calculated to be > 400°C. This value was confirmed by the consortium.
