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:
- 1985
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 103 (Boiling point/boiling range)
- GLP compliance:
- yes
- Type of method:
- method according to Siwoloboff
- Key result
- Decomposition:
- yes
- Decomp. temp.:
- > 220 - < 250 °C
- Boiling pt.:
- 109 °C
- Atm. press.:
- 11 Pa
- Remarks on result:
- other: Heat of evaporation= 82.9kJ/mol, measured by Thermogravimetry
- Boiling pt.:
- 314.85 °C
- Atm. press.:
- 1 013 hPa
- Remarks on result:
- other: Extrapolated using measured data by Thermogravimetry
- Conclusions:
- The test substance decomposes at >220°C before boiling
Reference
The determination of boiling point according to Siwoloboff was impossible, because of decomposition of the substance in the temperature region 220 - 250°C.
Observation during the determination:
1) Temperature region 25 - 242°C with heating rate ca. 17 K/min: change of color at about 220°C (colorless to yellow)
2) Temperature region 242 - 248°C with heating rate 0.5 K/min: substance has brown color and is turbid
3) Temperature region 248 - 250°C with heating rate 0.5 K/min: beginning of separation of brown, dark drops in the liquid
Evolution of gas can be seen in the temperature region above 242°C.
Description of key information
Decomposed at >220°C before boiling
Extrapolated 315°C at 1013 hPa for use in CSA
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 314.85 °C
- Temperature of decomposition (state purity):
- 220 °C
Additional information
The determination of boiling point according to Siwoloboff was not possible because of decomposition of the substance in the temperature region 220 - 250°C.
The boiling point was extrapolated using vapour pressure data measured by Thermogravimetry
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
