Results and discussion
Melting / freezing point
- Key result
- Decomposition:
- yes
- Decomp. temp.:
- >= 569 - <= 571 K
Any other information on results incl. tables
Similar thermographic profiles were obtained using air and nitrogen atmospheres; this indicates that the observed decomposition in the determinations is probably thermal and not oxidative.
Applicant's summary and conclusion
- Conclusions:
- The test material has been determined to decompose at approximately 569 to 571 K (295.5 to 298 °C), prior to melting.
