Results and discussion
Melting / freezing point
- Melting / freezing pt.:
- 170 °C
- Atm. press.:
- ca. 1 atm
- Decomposition:
- yes
- Decomp. temp.:
- ca. 337 °C
- Sublimation:
- no
Any other information on results incl. tables
An exothermic decomposition starts at 337°C. Because of the overlap of endothermic and exothermic processes, the energy measured for the exothermic process (312 J/g) is less than the true decomposition energy. The sharp endothermic peak at 170°C is the melting point.
Applicant's summary and conclusion
- Conclusions:
- The melting point of the substance is 170°C:
- Executive summary:
The melting point of the substance was determined by DSC and was found to be 170 °C.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
