Description of key information

- auto-ignition temperature = 227°C (CRC Handbook, 2005)

- auto-ignition temperature = 235°C (Yaws' Handbook, 2003)

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:
227 °C

Additional information

There are two literature sources of similar reliability with slightly deviating results:

According to the CRC Handbook, the auto-ignition temperature of Octadecane is 227°C. The other available auto-ignition temperature, reported from Yaws' Handbook, is in the same range, allowing the conclusion that the available data can be considered sufficiently reliable. The lower value was chosen as the key value.
