Measurement parameters

Maximum Temperature of Furnace:575°C

Measurement

Autoignition Temperature:269°C

Conclusions:
An auto-ignition temperature value of 269°C at standard pressure was determined for the substance using a relevant test method. The result is considered to be reliable.
Executive summary:

Octadecan-1ol was determined according ASTM D93. The flash point was determined to be 269 °C at atmospheric pressure.

Description of key information

The auto-ignition temperature of octadecan-1-ol is ca. 269°C at 1013 hPa.

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:
269 °C

Additional information

An auto-ignition temperature value of 269°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.

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.
