Results and discussion
Relative self-ignition temperature (solids)
- Key result
- Relative self-ignition temperature:
- ca. 129 °C
Applicant's summary and conclusion
- Conclusions:
- Determination of decomposition temperature with DTA (without O2 influence): approx 120°C.
Self-ignition temperature (with O2 influence): approx. 129°C.
The decomposition temperature is not reduced by Oxygen presence. The thermal instability is characterized by the decomposition reaction.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
