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.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
