- other: extrapolated onset temperature, mean of 2 determinations
Any other information on results incl. tables
No information is given on atmospheric pressure
Mean melting temperature: 181 +/- 1 °C (455 +/- 1 K)
After the experiments, the residue in the sample crucible was described as follows:
determination 1: Clear light brown film around the edge of the crucible base
determination 2: Light brown film, containing traces of solid, around the edge of the crucible base
Applicant's summary and conclusion
- Conclusions:
- The melting temperature of PF-6 was determined to be 181 ± 1 °C (455 ± 1 K) using differential scanning calorimetry.
