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:
- From 22 June 2003 to 3 July 2003
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 103 (Boiling point/boiling range)
- Deviations:
- yes
- Remarks:
- Sample pre-heated to 50°C to allow introduction into the boiling tube
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.2 (Boiling Temperature)
- Deviations:
- yes
- Remarks:
- Sample pre-heated to 50°C to allow introduction into the boiling tube
- Principles of method if other than guideline:
- Sample pre-heated to 50°C to allow introduction into the boiling tube
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- method according to Siwoloboff
- Boiling pt.:
- > 275 °C
- Atm. press.:
- 1 015 mBar
- Decomposition:
- yes
- Decomp. temp.:
- >= 275 °C
- Remarks on result:
- other: Substance decomposed above 275°C. No boiling observed.
- Conclusions:
- It was not possible to determine the boiling point of the registered substance as it decomposed at temperatures above 275 °C without boiling.
- Executive summary:
The boiling point of the registered substance was determined using OECD Test Method 103. The boiling point was evaluated using a modified Siwoloboff method at a heating rate of 1 °C/minute, but it was not possible to determine a boiling point due the test substance decomposing at temperatures above 275 °C. This was seen by the solution turning from its initial pale yellow appearance to a dark amber colour by 290 °C.
Reference
Description of key information
The study was performed on the registered substance. The boiling point could not be determined considering that the substance decomposed above 275 °C.
Key value for chemical safety assessment
Additional information
The study was performed on the registered substance. The boiling point of the test substance was to be evaluated in accordance with the OECD Guideline for Testing of Chemicals 103 using a modified Siwoloboff method. The boiling point could not be determined as the substance decomposed above 275 °C, turning from its pale yellow appearance to a dark amber colour before reaching its boiling point.
