Constituent 1
Results and discussion
Melting / freezing point
- Melting / freezing pt.:
- > 324 - <= 335 °C
- Atm. press.:
- ca. 1 atm
- Decomposition:
- yes
- Decomp. temp.:
- > 325 °C
- Remarks on result:
- other: The product begins to melt at 324°C. An exothermic decomposition starts at 325°C. Because of the overlap of endothermic and exothermic processes, the energy measured for the exothermic process (206 J/g) is less than the true decomposition energy.
Applicant's summary and conclusion
- Conclusions:
- The tested substance starts to melt at 324°C.
- Executive summary:
Melting of the tested substance starts at 324°C using a Differential Scanning Calorimeter.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
