Link to relevant study record(s)
- Endpoint:
- melting point/freezing point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2011-02-04 (experimental phase)
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: The study was conducted according to a relevant guideline without deviations. It was not carried out according to GLP, but it was performed in a test facility which has been certified to be in compliance with the principles of GLP.
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- Version / remarks:
- from May 30, 2008
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- Version / remarks:
- adopted July 27, 1995
- Deviations:
- no
- GLP compliance:
- no
- Remarks:
- However, the study was performed in a test facility which has been certified to be in compliance with the principles of GLP.
- Type of method:
- thermal analysis
- Melting / freezing pt.:
- 175.5 °C
- Atm. press.:
- ca. 1 atm
- Decomposition:
- no
- Sublimation:
- no
- Remarks on result:
- other: Atmospheric pressure is not reported, however it is assumed that the test was performed at ambient pressure.
- Conclusions:
- The melting point of the test item was determined to be 175.5 ± 0.5 °C. The study is considered to be adequate and reliable.
- Executive summary:
The determination of the melting point/melting range of the test item was performed according to the OECD Guideline No. 102: “Melting point / melting range“, adopted July 27, 1995 by thermal analysis.
In a preliminary test done by differential scanning calorimetry, an endothermic heat effect was observed starting at 177.8 °C. In order to determine the melting more precisely, further differential scanning calorimetry-runs were recorded between 120 °C and 220 °C with a heating rate of 10 °C/min during the main test. In the first main test run, the melting was observed at 175.3 °C, during the second main test run at 175.7 °C.
The melting point of the test item was determined to be 175.5 ± 0.5 °C.
Reference
Preliminary Test
An endothermic heat effect was observed starting at 177.8 °C. After the experiment, the sample had lost about 61% of its mass and a black carbonized foam residue remained.
Main Tests
In order to determine the melting more precisely, further differential scanning calorimetry-runs were recorded between 120 °C and 220 °C with a heating rate of 10 °C/min. In the first main test run, the melting was observed at 175.3 °C, during the second main test run at 175.7 °C. During these runs, the samples lost about 3% of their mass and a brown melt remained in the sample cups.
