Description of key information
The self-ignition temperature of undecan-1-ol is ca. 253°C.
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 253 °C
Additional information
The self-ignition temperature of ca. 253°C was determined in a reliable study.
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.
