Results and discussion
Boiling point
- Atm. press.:
- 101.3 kPa
- Decomposition:
- yes
- Decomp. temp.:
- ca. 226 °C
- Remarks on result:
- other: approximate onset temperature of decomposition
Any other information on results incl. tables
As a result of the low rate of enthalpy change during decomposition, the onset temperature can only be approximated.
As the test item decomposed, no value for boiling temperature could be determined.
After both experiments, the residue in the sample crucible was described as follows: dark brown.
Applicant's summary and conclusion
- Conclusions:
- Using differential scanning calorimetry, PF-6 was determined to decompose from approximately 226 °C (499 K) at 101.3 kPa. As the test item decomposed, no value for boiling temperature could be determined.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
