Results and discussion
Melting / freezing point
- Decomposition:
- yes
- Decomp. temp.:
- 300 °C
Any other information on results incl. tables
The exothermal (decomposition) reaction shows an onset at approximately 300 °C (taken as decomposition temperature) and a peak at 313.82 °C in the DTA curve, the reaction energy of the decomposition being -150 J/g (mean from 2 measurements).
No discernible endothermal reaction (melting) was seen in the DTA.
Applicant's summary and conclusion
- Conclusions:
- Decomposition starts without discernible melting, the decomposition temperature is 300 °C.
- Executive summary:
The DTA shows decomposition starting at 300 °C without discernible melting prior to decomposition.
