- Endpoint:
- melting point/freezing point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 13 December 2016
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- Version / remarks:
- 1995
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- Version / remarks:
- 2008
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- capillary method
- Key result
- Melting / freezing pt.:
- > 131 - < 134 °C
- Decomposition:
- yes
- Remarks on result:
- other: There was visual evidence of degradation simultaneous with melting. Hence this melting point evaluation may not be accurate.
- Conclusions:
- Under the conditions of this study the melting point is considered to be in the range of 131 °C - 134 °C but there was visual evidence of degradation simultaneous with melting. Hence this melting point evaluation may not be accurate.
- Executive summary:
The melting point of the test material was investigated in accordance with the standardised guidelines OECD 102 and EU Method A.1 under GLP conditions using the capillary method.
At about 131 °C the test material started to melt, but simultaneously a continuous formation of bubbles was observed. There were no solid particles about 134 °C, but there was a foam-like layer which formed on top of the liquid phase.
Under the conditions of this study the melting point is considered to be in the range about 131 °C - 134 °C but there was visual evidence of degradation simultaneous with melting. Hence this melting point evaluation may not be accurate.
Reference
Preliminary Test
- From 30 °C to approximately 171 °C at 10 °C/min heating rate with one aliquot sample: The test material started to melt at about 116 °C, but a white non-liquid substance remained in the capillary that did not disappear. These white particles were solid residue or foam-like layer, the visual change suggests that degradation took place before full melting. Therefore, the preliminary test was repeated with a slower heating rate in favour of more accurate results.
-From 70 °C to approximately 147 °C at 5 °C/min heating rate with one aliquot sample: The test material started to melt at about 124 °C, but the capillary still contained foam-like white residue. The preliminary test was repeated again with more a slower heating rate. The visual results indicated degradation before full melting.
- From 120 °C to approximately 200 °C at 2 °C/min heating rate with one aliquot sample: The test material started to melt at about 128 °C, but the capillary still contained foam-like white residue. The liquid phase turned brown at over 140 °C.
- From 125 °C to approximately 145 °C at 1 °C/min heating rate with two parallel samples: The test material started to melt about 132 °C, but the capillary still contained foam-like white residue. The liquid phase turns brown over 140 °C.
Main Test
-At about 131 °C the test material started to melt, but simultaneously a continuous formation of bubbles was observed. There were no solid particles about 134 °C, but there was a foam-like layer which formed on top of the liquid phase.
-The melting point is considered to be in the range about 131 °C - 134 °C but there was visual evidence of degradation simultaneous with melting. Hence this melting point evaluation may not be accurate.
Description of key information
Under the conditions of this study the melting point is considered to be in the range of 131 °C - 134 °C but there was visual evidence of degradation simultaneous with melting. Hence this melting point evaluation may not be accurate.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 131 °C
Additional information
The melting point of the test material was investigated in accordance with the standardised guidelines OECD 102 and EU Method A.1 under GLP conditions using the capillary method. The study was awarded a reliability score of 1 in accordance with the criteria set forth by Klimisch et al. (1997).
At about 131 °C the test material started to melt, but simultaneously a continuous formation of bubbles was observed. There were no solid particles about 134 °C, but there was a foam-like layer which formed on top of the liquid phase.
Under the conditions of this study the melting point is considered to be in the range about 131 °C - 134 °C but there was visual evidence of degradation simultaneous with melting. Hence this melting point evaluation may not be accurate.
