- other: ASTM E537-12 (mod.) Thermal Stability by DSC
- Deviations:
- no
- GLP compliance:
- no
- Type of method:
- differential scanning calorimetry
- Key result
- Decomposition:
- yes
- Decomp. temp.:
- 220 °C
- Conclusions:
- Under the conditions of this study, the test material decomposed at 220 °C, before boiling.
- Executive summary:
The boiling point of the test material was determined in accordance with the standardised guideline OECD 103, using differential scanning calorimetry, following ASTM E537 -12.
During the study, the prepared crucibles (crucible with test material and reference crucible) were placed in the DSC apparatus. Both crucibles were heated up from room temperature to 500 °C with a heating rate of 5 K/min.
No significant exothermic effects were observed up to 500°C. The onset of decomposition was at 193.8 °C, the peak was at 219.8 °C with + 5.9 J/g² energy (endotherm.).
It was therefore concluded the test material decomposed at 220 °C before boiling.

Results
- In the temperature range 25 – 500 °C endothermic effects were observed.
- The onset of decomposition was at 193.8 °C, the peak was at 219.8 °C with 5.9 J/g² energy (endotherm.)
- It was therefore concluded the test material decomposed at 220 °C before boiling.

Additional information
The boiling point of the test material was determined in accordance with the standardised guideline OECD 103, using differential scanning calorimetry, following ASTM E537 -12. The study was awarded a reliability score of 2 in accordance with the criteria set forth by Klimisch et al. (1997).
During the study, the prepared crucibles (crucible with test material and reference crucible) were placed in the DSC apparatus. Both crucibles were heated up from room temperature to 500 °C with a heating rate of 5 K/min.
No significant exothermic effects were observed up to 500°C. The onset of decomposition was at 193.8 °C, the peak was at 219.8 °C with + 5.9 J/g² energy (endotherm.).
It was therefore concluded the test material decomposed at 220 °C, before boiling.
