Results and discussion
Melting / freezing point
- Key result
- Decomposition:
- yes
- Decomp. temp.:
- >= 200 - <= 540 °C
- Sublimation:
- no
Any other information on results incl. tables
No melting peak (endothermic reaction) in DSC was observed.
Between 200 °C and 540 °C the DSC showed exothermic peaks with different intensity, which indicated further decomposition of the test substance. A loss of mass began at about 290 °C. At 540 °C about 98 % of the initial mass was lost.
Applicant's summary and conclusion
- Conclusions:
- A melting point cannot be determined.
