Results and discussion
Melting / freezing point
- Key result
- Remarks on result:
- not determinable
Any other information on results incl. tables
The sample was cooled to -150°C; rapidly for the first test, and controlled with a low cooling rate of -2 K/ min for the repeat measurement. Upon heating the heat flow curves of both tests show only a small glass transition at -86°C, indicating that the sample had solidified amorphously, regardless of cooling rate. No other thermal effect from crystallisation or melting was registered.
Applicant's summary and conclusion
- Conclusions:
- The melting temperature of the test item was determined by differential scanning calorimetry according to OECD guideline no. 102 (adopted on July 27, 1995) and EEC-Directive 92/69 EEC, Part A, Methods for the determination of physico-chemical properties, A.1 „Melting temperature"“, EEC Publication No. L383, December 1992
Melting point: no melting point. - Executive summary:
extrapolated onset temperature [°C] boiling temperature [°C] at 1013 hPa First run 359.10 358.86 Second run 358.61 360.12 Mean value 359.49
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
