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:
- 11th May 2018 to 10th December 2018
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 103 (Boiling Point)
- Version / remarks:
- Version of 27th July 1995
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.2 (Boiling Temperature)
- Version / remarks:
- Version of 31th May 2008
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- differential scanning calorimetry
- Specific details on test material used for the study:
- - Name: 6-sec-butylquinoline
- Purity by GLC: > 99.2%
- Lot number: 6SBQ5/2017
- Molecular formula: C13H15N
- Molecular weight: 185.26955 g/mol - Key result
- Decomposition:
- yes
- Decomp. temp.:
- ca. 315 °C
- Remarks on result:
- not determinable
- Remarks:
- observed boiling is the boiling point of the decomposition product.
- Conclusions:
- Boiling was observed at 315°C, but beginning colour change of the test item was visible from 168°C, as shown in the following figure below. Therefore, no main test was performed.
- Executive summary:
In the pre-test following Siwoloboff decomposition was observed indicated by colour change before boiling stage, therefore no boiling point can be determined. The observed boiling is the boiling point of the decomposition product.
Reference
| Temperature °C | Observations |
| 69 | Singular bubbles rose |
| 115 | More bubbles visible |
| 130 | Condensate visible |
| 168 - 233 | No bubbles anymore, colour of test item getting darker |
| 234 | Colour is dark yellow, some bubbles again |
| 264 | Divers more bubbles |
| 315 | Bubble chain, gas burner switched off (but heated until 320°C). Bubble chain immediately broke and no bubbles were visible anymore. |
Boiling was observed at 315°C, but beginning colour change of the test item was visible from 168°C. The observed boiling is the boiling point of the decomposition product.
Description of key information
In the pre-test following Siwoloboff decomposition was observed indicated by colour change before boiling stage, therefore no boiling point can be determined. The observed boiling is the boiling point of the decomposition product.
Key value for chemical safety assessment
