Melting point / freezing point
Administrative data
Link to relevant study record(s)
- Endpoint:
- melting point/freezing point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 14.February 20212
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: Guideline study with acceptable restrictions. Valid method according to company guideline /standard operating procedure
- Principles of method if other than guideline:
- Differential thermal analysis (DTA)
- Type of method:
- other: Differential scanning colorimetry (DSC)
- Key result
- Melting / freezing pt.:
- 269 °C
- Decomposition:
- yes
- Decomp. temp.:
- 276 °C
- Executive summary:
The DTA recorded a melting point of 269°C and decomposition from the melting substance at onset temperature of 276°C.
Reference
An exothermic decomposition starts at 276°C. Because of the overlap of endothermic and exothermic processes, the energy measured for the exothermic process (945 J/g) is less than the true decomposition energy. The product begins to melt at 269°C.
Description of key information
Melting point at 269°C. Thermal analysis (Differential scanning colorimetry (DSC)).
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 269 °C
