Date: 2009 -11 -30

Operator: J.Wolter

certified reference sample: n-Dodecan

self ignition temperature (theory) in °C: 205

self ignition temperature (experimental) in °C: 206

atmospheric pressure in mBar: 1006.0


(repeat determination)

self ignition temperature in °C: 254 / 256

atmospheric pressure in mBar: 1007 / 1008

An auto-ignition temperature value of 255°C was determined for the substance using a relevant test method. The result is considered to be reliable.
Executive summary:

Icosan-1-ol was determined according DIN 51794. The self ignition temperature was determined to be 255 °C at atmospheric pressure.

Description of key information

The auto-ignition temperature of icosan-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 was determined 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.
