Key result
Auto-ignition temperature:
ca. 294 °C
Atm. press.:
ca. 1 013 mBar
Conclusions:
An auto-ignition temperature value of 294°C at 1013 hPa was determined for the substance using a relevant test method. The result is considered to be reliable.
Executive summary:

Octan-1-ol was determined according ASTM E 659. The selfignition point was determined to be 294 °C at atmospheric pressure.

Description of key information

The auto-ignition temperature of octan-1-ol is 294°C at 1013 hPa.

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:
294 °C

Additional information

An auto-ignition temperature value of 294°C at 1013 hPa was determined in accordance with ASTM E 659. The result is considered to be reliable and is selected as key study.

It is supported by a value of 253°C, taken from a source of hazard reference data (the online International Chemical Safety Cards of WHO IPCS).

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.
