The auto ignition temperature was found to be 256°C using a relevant test method. The result is considered to be reliable.
Executive summary:

Docosan-1-ol was determined according DIN 51794. The self ignition temperature was determined to be 256 °C at atmospheric pressure.

Description of key information

The auto-ignition temperature of docosan-1-ol is 256°C at 1013 hPa.

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:
256 °C

Additional information

An auto-ignition temperature of 256°C at 1013 hPa was determined for the substance in accordance with DIN 51794. The result is considered to be reliable.

Discussion of trends in the Category of C6-24 linear and essentially-linear aliphatic alcohols:

As carbon number increases, auto-ignition temperature generally decreases. Molecular weight is higher and intermolecular forces in the substance are all higher.
