Results and discussion

Melting / freezing point
Melting / freezing pt.:
ca. 200 °C
Atm. press.:
ca. 1 atm
Decomposition:
yes
Decomp. temp.:
ca. 200 °C
Remarks on result:
other: The substance decomposes before melting

Applicant's summary and conclusion

Conclusions:
The substance shows no melting point. It decomposes at about 200 °C.
Executive summary:

It was tried to determine the melting point of the substance by DSC ( Mettler-Toledo 821e, 25 – 450°C, 3 K/min, sealed glass vial in air).

The product starts to decompose in the sealed vial at 200°C with a mean energy of 860 J/g. No melting was observed..
