Results and discussion

Melting / freezing point
Melting / freezing pt.:
334 °C
Atm. press.:
ca. 1 atm
Decomposition:
yes
Decomp. temp.:
>= 436 °C
Remarks on result:
other: The product starts to decompose in the sealed vial at 436°C. The decomposition energy could not be determined as the process is not complete at 450°C.

Applicant's summary and conclusion

Conclusions:
The tested melting point is 334°C.
Executive summary:

The melting point was determined using a Differential Scanning Calorimeter.
