Results and discussion

Auto-ignition temperature (liquids / gases)
Key result
Auto-ignition temperature:
390 °C
Atm. press.:
>= 764.538 - <= 770.613 mm Hg
Remarks on result:
other: auto-ignition likely due to reaction during decomposition

Any other information on results incl. tables

The average lowest temperature that ignition was observed to be 393.99 °C, which is greater than the decomposition temperature determined in the boiling point test. Following DIN 51794 guidelines, the auto-ignition temperature would be considered 390 °C. The auto-ignition temperature observed is dependent on the mass of the sample, which impacts the thermal transfer and kinetic properties during decomposition. Although auto-ignition was observed, the resulting flame was most likely due to the generation and ignition of gaseous degradation material produced during decomposition.

Applicant's summary and conclusion

Conclusions:
The auto ignition of DiBrORMA was determined to be 390 °C at 764.538 - 770.613 mmHg (ASTM E659).
Executive summary:

The auto ignition temperature of DiBrORMA was determined to be 393.99 °C. This value was rounded down to 390 °C per guideline. The auto-ignition temperature was dependent on the mass of the sample, which impacts the thermal transfer and kinetic properties during decomposition. It is also likely the resulting flame was due to the generation and ignition of gaseous degradation material produced during decomposition. The study was conducted in accordance with ASTM E659 and was GLP compliant. Therefore, the study is considered reliable without restrictions.
