Results and discussion
Melting / freezing point
- Atm. press.:
- 101.325 kPa
- Decomposition:
- yes
- Decomp. temp.:
- > 275 °C
- Remarks on result:
- other: A small glass transition peak was observed between -75°C and -50°C.
Any other information on results incl. tables
In the DSC curve recorded during the heating of the test substance (-90 °C - 349 °C) a small glass transition peak was observed between -75 °C and -50 °C. An endothermic effect was observed from 275 °C. This effect was caused by reaction/decomposition of the test substance.
After the experiment, a yellow/brown coloured residue remained in the sample container.
Applicant's summary and conclusion
- Conclusions:
- Reaction and/or decomposition of the test substance were observed above approximately 275°C (548K): melting and/or boiling of the test substance were not observed below the temperature at which reaction and/or decomposition started. Within the scope of this test, the test substance has no melting and/or boiling temperature.
- Executive summary:
The determination of the melting point was carried out according to OECD guide line 102. In the DSC curve recorded during the heating of the test substance (-90 °C - 349 °C) a small glass transition peak was observed between -75 °C and -50 °C. An endothermic effect was observed from 275 °C. This effect was caused by reaction/decomposition of the test substance. Reaction and/or decomposition of the test substance were observed above approximately 275°C (548K). Melting and/or boiling of the test substance were not observed below the temperature at which reaction and/or decomposition started. Within the scope of this test, the test substance has no melting and/or boiling temperature.
