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:
- 07/15/2021 - 07/30/2021
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study with acceptable restrictions
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.2 (Boiling Temperature)
- Version / remarks:
- Council Regulation (EC) No 440/2008 of 30 May 2008
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 103 (Boiling Point)
- GLP compliance:
- no
- Type of method:
- differential scanning calorimetry
- Key result
- Boiling pt.:
- 276 °C
- Atm. press.:
- 1 013 hPa
- Decomposition:
- yes
- Decomp. temp.:
- 276 °C
- Remarks on result:
- other: The substance undergoes boiling with decomposition
- Conclusions:
- The substance was found to undergo boiling with decomposition at 276°C using an appropriate guideline method not according to GLP. This result is considered reliable.
Reference
No normal boiling point was found.
A partial boiling of the main compound starts at around 276 °C, probably already associated with decomposition.
Description of key information
Boiling point/decomposition temperature: 276°C at 1013 hPa (OCED 103)
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 276 °C
- Temperature of decomposition (state purity):
- 276 °C
Additional information
The substance was found to undergo boiling with decomposition at 276°C using a differential scanning calorimetry method according to OECD Test Guideline 103. This result is considered reliable and is selected as key.
A predicted boiling point of 300°C at 1013 hPa was determined for the substance using an accepted QSAR estimation method. The result is considered to be reliable and is selected as key study.
In a secondary source to which no reliability could be assigned, a boiling point of 96°C at a very low pressure of 0.1 mmHg (13 Pa) was reported for the substance.
