Boiling point
Administrative data
Link to relevant study record(s)
- Endpoint:
- boiling point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 27 April 2018
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study with acceptable restrictions
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 103 (Boiling Point)
- Version / remarks:
- 1995
- Deviations:
- no
- GLP compliance:
- no
- Type of method:
- differential scanning calorimetry
- Key result
- Decomposition:
- yes
- Decomp. temp.:
- 248 °C
- Conclusions:
- Under the conditions of this study the boiling point cannot be determined since the test material decomposes at 248 °C.
- Executive summary:
The boiling point of the test material was investigated in accordance with the standardised guideline OECD 103, using differential scanning calorimetry.
The test material shows an endothermic process at 29 °C, the melting point. A second endothermic process at 80 °C can be assigned to a rearrangement of the cyclic ligand of the test material. The test material then decomposes at 248 °C
Under the conditions of this study the boiling point cannot be determined since the test material decomposes at 248 °C.
Reference
- The test material shows an endothermic process at 29 °C, the melting point. A second endothermic process at 80 °C can be assigned to a rearrangement of the cyclic ligand of the test material.
- The test material decomposes at 248 °C
- The boiling point can not be determined since the test material rearranges at 80 °C and finally decomposes at 248 °C.
Description of key information
Under the conditions of this study the boiling point cannot be determined since the test material decomposes at 248 °C.
Key value for chemical safety assessment
Additional information
The boiling point of the test material was investigated in accordance with the standardised guideline OECD 103, using differential scanning calorimetry. The study was awarded a reliability score of 2 in accordance with the criteria set forth by Klimisch et al. (1997).
The test material shows an endothermic process at 29 °C, the melting point. A second endothermic process at 80 °C can be assigned to a rearrangement of the cyclic ligand of the test material. The test material then decomposes at 248 °C
Under the conditions of this study the boiling point cannot be determined since the test material decomposes at 248 °C.
