Melting point / freezing point
Administrative data
Link to relevant study record(s)
- Endpoint:
- melting point/freezing point
- Type of information:
- other: Company Data
- Adequacy of study:
- key study
- Study period:
- Not specified
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- study well documented, meets generally accepted scientific principles, acceptable for assessment
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- Dynamic differential scanning calorimetry was used to determine the melting point of the test material.
- GLP compliance:
- no
- Type of method:
- differential scanning calorimetry
- Key result
- Melting / freezing pt.:
- >= 210 - <= 250 °C
- Decomposition:
- yes
- Remarks:
- Complex multi-step decomposition takes place before and after the melting point
- Conclusions:
- Under the conditions of this study the melting point of the test material was from 210 to 250 °C.
- Executive summary:
Dynamic differential scanning calorimetry was used to determine the melting point of the test material.
An exothermal decomposition above 208 °C during and after the melting with medium power (DH = -370 J/g -> adiabatic temperature rise DTad = 205K) was detected.
In the Grewer oven no significant exotherm was detected up to the melting point at approx. 210°C.
Under the conditions of this study the melting point of the test material was from 210 to 250 °C.
