- Decomposition:
- yes
- Decomp. temp.:
- 100 - 340 °C
- Remarks on result:
- not determinable
- Conclusions:
- Under the test conditions, the test substance shows no boiling point in the temperature range of 25-400 °C only an exothermic decomposition beginning at 100 °C.
- Executive summary:
The boiling point/range of the test substance was determined in accordance with the EU Method A.2. in compliance with GLP.
The test performed by using DSC, Mettler-Toledo TA8000, in a closed glass pan.
Two measurements in a closed glass pan does not show any endothermic effect prior an exothermal decomposition was observed in the range 100-340 °C, with a decomposition energy of 691 J/g respectively 636 J/g.
Under the test conditions, the test substance shows no boiling point in the temperature range of 25-400 °C only an exothermic decomposition beginning at 100 °C.
