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:
- Start date of the experimental work: 23 August 2018 and Completion date of the experimental work: 31 October 2018.
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 103 (Boiling Point)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.2 (Boiling Temperature)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- other: SIWOLOBOFF method and Differential Scanning Calorimeter method.
- Remarks:
- As no boiling point was observed at 250°C which exceeds the limitation of the apparatus, the DSC method was used for boiling point determination.
- Key result
- Boiling pt.:
- >= 351.7 - <= 357.4 °C
- Atm. press.:
- 101.6 kPa
- Decomposition:
- no
- Conclusions:
- No boiling was observed at 250°C, which exceeds the limitation of the apparatus (SIWOLOBOFF method). Therefore the Differential Scanning Calorimetry method was used and the boiling point was determined to be in the range: 351.7 - 357.4°C
- Executive summary:
The test is conducted to determine the temperature or temperature range of the phase transition from a liquid to a vapour. The test also determines if the sample undergoes exothermic decomposition.
The test is conducted in accordance with the procedure described in EU Regulation (EC) 440/2008, Annex Part A test A.2 and OECD Test Guideline 103.
No boiling was observed at 250°C, which exceeds the limitation of the apparatus (SIWOLOBOFF method). Therefore the Differential Scanning Calorimetry method was used and the boiling point was determined to be in the range: 351.7 - 357.4°C
