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:
- 17 Sep 2014 to 28 Oct 2014
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 103 (Boiling point/boiling range)
- Version / remarks:
- July 1995
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.2 (Boiling Temperature)
- Version / remarks:
- May 2008
- Deviations:
- no
- GLP compliance:
- no
- Remarks:
- The study was carried out in a laboratory accredited under GLP, however the study itself was not subject to GLP audit.
- Type of method:
- differential scanning calorimetry
- Key result
- Atm. press.:
- >= 100.5 - <= 101.3 kPa
- Decomposition:
- yes
- Decomp. temp.:
- >= 284 °C
- Remarks on result:
- not determinable
- Remarks:
- Due to thermal decomposition.
- Conclusions:
- In a valid, reliable and conclusive study according to OECD TG 103 (1995) and Method A2 (EC) No 440/2008, the boiling temperature of the test item was determined. The test item boiled partially, with decomposition, from approximately 284 °C (557 K) at 100.5 to 101.3 kPa. Decomposition was observed both in air and under a nitrogen atmosphere. Therefore, due to thermal decomposition, a definitive boiling point cannot be determined.
- Executive summary:
The study was performed to determine the boiling temperature of the test item according to OECD TG 103 (1995) and Method A2 (EC) No 440/2008. The test item boiled partially, with decomposition, from approximately 284 °C (557 K), at 100.5 to 101.3 kPa. Decomposition was observed both in air and under a nitrogen atmosphere. Therefore, due to thermal decomposition, a definitive boiling point cannot be determined.
