Description of key information
The self-ignition temperature of tetracosan-1-ol is 255°C.
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 255 °C
Additional information
An auto-ignition temperature value of 255°C at 1013 hPa was determined in accordance with DIN 51791. 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.
