- Key result
- Melting / freezing pt.:
- 341 °C
- Decomposition:
- yes
- Decomp. temp.:
- 445 °C
- Remarks on result:
- other: no information on atm pressure provided
- Conclusions:
- Under the conditions of this study, the test material melted at 341 °C .
- Executive summary:
The melting point of the test material was determined in accordance with the standardised guideline OECD 102, using differential scanning calorimetry.
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.
The onset of melting was at 339.4 °C, the peak was at 341.1 °C with + 14.9 J/g² energy (endotherm.).
Under the conditions of this study, the test material melted at 341 °C .
Reference
- The onset of melting was at 339.4 °C, the peak was at 341.1 °C with + 14.9 J/g² energy (endotherm.).
- The test material melted at 341 °C .
Description of key information
Under the conditions of this study, the test material melted at 341 °C .
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 341 °C
Additional information
The melting point of the test material was determined in accordance with the standardised guideline OECD 102, using differential scanning calorimetry. The study was awarded a reliability score of 2 in accordance with the criteria set forth by Klimisch et al. (1997).
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.
The onset of melting was at 339.4 °C, the peak was at 341.1 °C with + 14.9 J/g² energy (endotherm.).
Under the conditions of this study, the test material melted at 341 °C .
