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.
