Results and discussion
Melting / freezing point
- Melting / freezing pt.:
- 187 °C
- Atm. press.:
- ca. 1 atm
- Decomposition:
- yes
- Decomp. temp.:
- >= 270 °C
- Remarks on result:
- other: The product starts to decompose in the sealed vial at 270°C with a mean energy of 108 J/g.Due to the irregular base line, there is considerable uncertainty in the decomposition energy.The endothermic peak between 188°C and 262°C is the main melting point
Applicant's summary and conclusion
- Conclusions:
- The tested melting point is 187°C.
- Executive summary:
The melting point was determined using a capillary method device.
The decomposition was determeined by Differential Scanning Calorimetry.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
