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:
- 6 Feb - 13 Mar 2002
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- Version / remarks:
- Test method A.I (section 1.4.4.1), "determination of the melting
point", described in the EG- guideline 92/69. - Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- thermal analysis
- Remarks:
- The sample is closed up in a crucible made of aluminium. The sample is cooled down in liquid nitrogen and then heated up in a DTA-system (heating rate 1 K/min). In comparison with an inert sample the temperature difference and the heat effect is recorded.
- Key result
- Melting / freezing pt.:
- 17.5 °C
- Decomposition:
- no
- Sublimation:
- no
- Remarks on result:
- other: No atmospheric pressure is stated.
- Conclusions:
- The melting point of the test substance is 17.5°C.
Up to a temperature of 300 °C there is no thermal decomposition of the test substance. - Executive summary:
The melting point of the test substance is 17.5°C.
Up to a temperature of 300 °C there is no thermal decomposition of the test substance.
Reference
The key value is the mean of four measured values - two were determined in closed and two in open crucible:
17.0°C ; 17.4°C (closed crucible)
17.7 °C ; 17.7 °C (open crucible).
Up to a temperature of 300 °C there is no thermal decomposition of the test substance (measured with Differential Thermal Analysis: The sample is closed up in a crucible made of glass. The sample is heated up in a DTA-system (heating rate 5 K/min). In comparison with an inert sample (empty crucible) the temperature difference and the heat effect is recorded. Any thermal effect corresponds to a baseline deviation).
Validity criteria for the measurement of the melting point:
Target condition according to guideline: | Actual condition according to the study: | Validity criteria met: |
The heating rate should not exceed 2 K/min. | Heating rate 1 K/min. | Yes |
The mean of at least two measurements which are in the range of the estimated accuracy is reported as the melting temperature. | Two values were determined, each in closed and open crucible. | Yes |
If the substance decomposes or sublimes before the melting temperature is reached, the temperature at which the effect is observed shall be reported. | The test substance was heated up to a temperature of 300°C - no thermal decomposition was observed. | Yes |
Description of key information
The melting point of the test substance is 17.5 °C.
Up to a temperature of 300 °C there is no thermal decomposition of the test substance.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 17.5 °C
