Results and discussion
Boiling point
- Boiling pt.:
- > 360 K
- Atm. press.:
- 101.46 kPa
- Decomposition:
- yes
- Remarks:
- gradual decomposition
- Decomp. temp.:
- <= 517 K
- Remarks on result:
- other: value is a calculated boiling point
Any other information on results incl. tables
No discernable onset temperature was observed by DSC. Therefore onset temperarure was assessed by visual estimate.

Applicant's summary and conclusion
- Conclusions:
- The test material has been determined to decompose gradually from 517 K at 101.46 kPa. As the test material decomposed, no value for the boiling point could be determined. A calculated value of boiling temperature gave a result of greater than 633 K.
