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:
- 11 August 2010
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: GLP, carried out according to recognised guideline
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.2 (Boiling Temperature)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 103 (Boiling point/boiling range)
- Deviations:
- no
- Principles of method if other than guideline:
- For the determination of the boiling point, the capillary method is used. A small amount of the test item is heated in the electronic controlled sample block and the temperature around the sample is displayed. The sample is observed visually while raising the temperature. A phase transformation from liquid to vapour usually is deduced by the formation of bubbles. The test item is assessed visually for any possible changes in its appearance, consistency and colour. The initial temperature of boiling or other effects observed is registered with the corresponding heating temperature.
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- other: capillary method
- Key result
- Boiling pt.:
- > 400 °C
- Atm. press.:
- 98 kPa
- Decomposition:
- no
- Remarks on result:
- other: No boiling point was observed at up to 400 deg C
- Conclusions:
- No boiling point was observed up to 400 °C.
- Executive summary:
An attempt was made to determine the boiling point of Reofos 65. No boiling point was observed up to 400 °C.
Reference
The test was carried out at 98.0 kPa atmospheric pressure. Using a linear heating rate of 0.5 °C/min, the boiling point of Reofos 65 was found to be: no boiling point was observed up to 400°C .
During the tests the following transformation temperature was recorded: Temperature 1. (399 °C): formulation of bubbles started
Description of key information
Boiling point
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 400 °C
Additional information
A single GLP compliant study gives the boiling point as >400 °C
