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:
- 2017
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study with acceptable restrictions
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- GLP compliance:
- no
- Type of method:
- thermal analysis
- Remarks:
- Differential Thermal Analysis (DTA)
- Key result
- Melting / freezing pt.:
- 102.3 °C
- Remarks on result:
- other: mean of four determinations, twice in an open and twice in a closed crucible
- Conclusions:
- The melting temperature of Epoxid-Valerat was 102.3 °C and no pressure was reported.
- Executive summary:
A differential thermoanalysis method (DTA) was used to determine the melting point which conforms with the procedure Test method A.1, "Determination of the melting point", described in the EC-Guideline. The melting temperature of Epoxid-Valerat was 102.3 °C and no pressure was reported. Between 210 °C and approx. 300 °C an exothermic phase could be detected. The melting process was found not to be reversible. After cooling down a one-time melted sample the melting point could not be reproduced.
