- Endpoint:
- boiling point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 28 July 2017 to 05 October 2017
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 103 (Boiling Point)
- Version / remarks:
- 1995
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.2 (Boiling Temperature)
- Version / remarks:
- 2008
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- differential scanning calorimetry
- Key result
- Atm. press.:
- 101 kPa
- Decomposition:
- yes
- Decomp. temp.:
- 191 °C
- Conclusions:
- Under the conditions of this study, determination of the boiling temperature was not possible, since the test material was found to react/decompose from 191 ± 0.5 °C (464 ± 0.5 K) at approximately 101 kPa.
- Executive summary:
The boiling point of the test material was investigated in accordance with the standardised guidelines OECD 103 and EU Method A.2, under GLP conditions using differential scanning calorimetry.
Aliquots of test material were placed in crucibles and were subjected to several thermal programs under an air atmosphere. During the experiments, the difference in heat flow between the sample crucible and the reference crucible (empty) was measured and recorded by the instrument.
The test material was assessed initially as an off white powder. The appearance of the residues after thermal analysis (recorded on each thermogram) and the crucibles’ weight loss confirmed decomposition of the test material with volatilisation.
Under the conditions of this study, determination of the boiling temperature was not possible, since the test material was found to react/decompose from 191 ± 0.5 °C (464 ± 0.5 K) at approximately 101 kPa.

Discussion
- The test material was assessed initially as an off white powder. The appearance of the residues after thermal analysis (recorded on each thermogram) and the crucibles’ weight loss confirmed decomposition of the test material with volatilisation.
- Determination of the boiling temperature was not possible, since the test material was found to react/decompose from 191 ± 0.5 °C (464 ± 0.5 K) at approximately 101 kPa.
Description of key information
Under the conditions of this study, determination of the boiling temperature was not possible, since the test material was found to react/decompose from 191 ± 0.5 °C (464 ± 0.5 K) at approximately 101 kPa.
Key value for chemical safety assessment
Additional information
The boiling point of the test material was investigated in accordance with the standardised guidelines OECD 103 and EU Method A.2, under GLP conditions using differential scanning calorimetry. The study was awarded a reliability score of 1 in accordance with the criteria set forth by Klimisch et al. (1997).
