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:
- 25 July 2019 to 26 July 2019
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 103 (Boiling Point)
- Version / remarks:
- 27 July 1995
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.2 (Boiling Temperature)
- Version / remarks:
- 31 May 2008
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- method according to Siwoloboff
- Key result
- Atm. press.:
- >= 97.4 - <= 98.1 kPa
- Decomposition:
- yes
- Decomp. temp.:
- ca. 100 °C
- Remarks on result:
- other: The test material became liquid from about 95 °C and an apparent degradation process with colour change from about 100 °C, with gas release from about 275 °C was recorded (the gas appeared to be related to degradation rather than classical boiling).
- Conclusions:
- No defined boiling point of the test material was determined in the study, as no exact boiling behaviour was observed. The test material became liquid from about 95 °C and an apparent degradation process with colour change from about 100 °C, with gas release from about 275 °C was recorded (the gas appeared to be related to degradation rather than classical boiling).
- Executive summary:
The boiling point of the test material was investigated in a study which was conducted in accordance with the standardised guidelines OECD 103 and EU Method A.2, under GLP conditions, following the Siwoloboff method.
During the study a small amount of the test material was used to fill a glass tube and was heated at a rate of 0.5 °C/minute.
During the controlled heating the appearance, consistency and colour of the sample were observed and recorded.
No defined boiling point of the test material was determined in the study, as no exact boiling behaviour was observed. The test material became liquid from about 95 °C and an apparent degradation process with colour change from about 100 °C, with gas release from about 275 °C was recorded (the gas appeared to be related to degradation rather than classical boiling).
