Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Conclusions:
The self ignition temperature is >400°C
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

Hydrocarbons, C9-C10, aromatics, >1% Naphthalene are a combination of Hydrocarbons, C9 Aromatics and Hydrocarbons, C10-C12 Aromatics. Read across data is available for Hydrocarbons, C9 Aromatics and Hydrocarbons, C10-C12 Aromatics and the worst case scenario for each end point has been presented.

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

The autoignition temperature of Hydrocarbons, C10, aromatics, >1% naphthalene is >400°C according to published material.

 

This data is used for read across to Hydrocarbons, C9-C10, aromatics, >1% Naphthalene.

Key value for chemical safety assessment

Additional information

The auto flammability of the Hydrocarbons, C9, aromatics was calculated to be >400°C.

 

The autoignition temperature of Hydrocarbons, C10, aromatics, >1% naphthalene is >400°C according to published material.
