Any other information on results incl. tables
Three DSC measurements were performed.
In all measurements an endothermic event with lowering of the baseline was detected.
Based on observations in the pre-test, lowering of the baseline and the appearance of the test item in the crucible after measurement a boiling under decomposition can be assumed.
This was evaluated with the onset function also the beginning and the end of the event were evaluated with the event marker function.
Therefore boiling under decomposition will be given in a range from 285.40 °C to 289.98°C in a boiling process from 257.90 °C to 307.41 °C with a peak maximum of 297.54°C.
Applicant's summary and conclusion
- Conclusions:
- According to OECD 103 resp. EU A.2, the range of the boiling process for the test item was detected from 257.90 to 307.41°C at standard pressure of 101.325 kPa.
