Key result
Auto-ignition temperature:
430 °C
Atm. press.:
101.8 kPa

As determined by this method, the AIT is the lowest temperature at which the substance will produce hot flame ignition in air at atmospheric pressure without the aid of an external ignition source such as spark or flame. It is the lowest temperature to which a combustible mixture must be raised so that the rate of heat evolved by the exothermic oxidation reaction will exceed the rate at which heat is lost to the surroundings and cause ignition. Autoignition, by its very nature, is dependent on the chemical and physical properties of the material and the method and apparatus employed for its determination. The autoignition temperature by a given method does not necessarily represent the minimum temperature at which a given material will self ignite. The volume of the vessel used is particularly important since lower autoignition temperatures will be achieved in larger vessels

The autoignition temperature of this substance has been determined to be 430°C.
