Results and discussion
Boiling point
- Key result
- Boiling pt.:
- >= 300.9 - <= 364.1 °C
- Atm. press.:
- ca. 1 013 hPa
Applicant's summary and conclusion
- Conclusions:
- Testing results give a boiling point in the range from 300.91 °C to 364.10 °C.
- Executive summary:
The determination of boiling point was determined via DSC (differential scanning calorimetry).
In both runs two endothermic events were detected.
Based on the pre-test for boiling point the first endothermic event can be identified as melting
point with 79.11 ± 0.25 °C.
The second endothermic event with decreasing baseline can be assigned as boiling under
decomposition which is giving in a range from 300.91 °C to 364.10 °C.
The appearance changes of the test substance after measurement confirms this.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
