Results and discussion
Vapour pressure
- Temp.:
- 25 °C
- Vapour pressure:
- ca. 0 Pa
- Remarks on result:
- other: estimate
Transition / decomposition
- Transition / decomposition:
- yes
- Transition temp.:
- > 230 °C
Any other information on results incl. tables
The substance decomposes at temperatures above 230 °C, thus the boiling point was calculated to be about 1150 °C using the Meissner's method. Based on the calculated boiling point, the vapour pressure of the substance was determined by calculation to be 2.1E-47 Pa at 25 °C using the Modified Watson Correlation.
Applicant's summary and conclusion
- Conclusions:
- The vapour pressure was calculated to be 2.1E-47 Pa at 25 °C.
