Results and discussion

Melting / freezing point
Melting / freezing pt.:
310 °C
Decomposition:
yes
Decomp. temp.:
315 °C

Any other information on results incl. tables

The substance begins to melt at 310°C (taken as melting point). An exothermic decomposition starts at 315°C (taken as decomposition temperature). Because of the overlap of endothermic and exothermic processes, the energy measured for the exothermic process (402 J/g) is less than the true decomposition energy.

Applicant's summary and conclusion

Conclusions:
The test item has a melting point of 310 °C and a decomposition temperature of 350 °C.
Executive summary:
The melting point was determined by DSC to be 310 °C with a decomposition temperature of 315 °C.
