Results and discussion

Melting / freezing point
Decomposition:
yes
Decomp. temp.:
ca. 288 °C

Any other information on results incl. tables

There is no endothermic effect (melting/boiling) in the DSC curves before decomposition.

The product starts to decompose in the sealed vial at ca. 288 °C with a mean energy of 101 J/g (2 measurements).

Applicant's summary and conclusion

Conclusions:
The test substance does not melt. Decomposition takes place at ca. 288 °C.
Executive summary:

The thermal behaviour of the test substance was investigated by Differential Scanning Calorimetry (DSC). The test substance does not melt. Decomposition takes place at ca. 288 °C.
