Results and discussion
Boiling point
- Boiling pt.:
- 667 K
- Decomposition:
- yes
- Remarks:
- demonstrated by black residue in the crucible
- Remarks on result:
- other: Similar thermographic profiles were obtained in air and nitrogen atmospheres indicating that the observed decomposition is probably thermal and not oxidative.
Any other information on results incl. tables

Applicant's summary and conclusion
- Conclusions:
- The test material has been determined to boil with decomposition from 667 ± 0.5K at 99.98 kPa
- Executive summary:
The boiling temperature has been assessed using Differential Scanning Calorimetry (DSC) according to EU method A2 in compliance with GLP. Using a calibrated Differential Scanning Calorimeter, the temperature at which an endotherm event equivalent to the boiling temperature recorded in duplicate. Taking an average of the recorded exothermic events, the boiling temperature was determined to onset at 667±0.5K with decomposition, as evidenced by black residue in the crucible after each determination.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
