Results and discussion

Melting / freezing point
Melting / freezing pt.:
115 °C
Atm. press.:
ca. 1 atm
Decomposition:
yes
Decomp. temp.:
>= 288 °C
Remarks on result:
other: The substance starts to decompose in a sealed vial at 288°C (apparatus: Mettler Toledo, DSC 821e) . The decomposition energy could not be determined precisely as the process is not complete at 450°C (decomposition energy > 1760 J/g).)

Applicant's summary and conclusion

Conclusions:
The tested melting point is 115 °C.
Executive summary:

The melting point was determined using a Differential Scanning Calorimeter.
