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:
- Test dates: Aug.6, 2010 to Feb.4, 2011
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study with acceptable restrictions
- Remarks:
- The study was conducted according to an internationally recognised method, and under GLP, with deviations in test conditions. The substance is adequately identified, but some data on composition is missing. Therefore validation applies with restrictions.
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.2 (Boiling Temperature)
- Deviations:
- yes
- Remarks:
- the measurement was performed using sealed crucibles
- GLP compliance:
- yes (incl. QA statement)
- Remarks:
- GIPC; effective July 24, 2009 (validity 18 months, postponed to Feb.28, 2011)
- Type of method:
- differential scanning calorimetry
- Specific details on test material used for the study:
- Storage conditions of test material: Room temperature protected from direct sun light.
- Key result
- Boiling pt.:
- ca. 224.3 °C
- Atm. press.:
- >= 1 atm
- Decomposition:
- no
- Executive summary:
The boiling point of the test substance was determined under GLP according to EU A2 guideline, using Differential Scanning Calorimetry (DSC) method.
Due to experimental issues, closed crucibles were used, which is not considered suitable for the determination of boiling. However, the result was consistent with QSAR estimation, and therefore considered acceptable as an approximate, minimum value.
The boiling temperature of the test substance was determined to be ca (>=) 224.3°C.
Reference
The boiling point was difficult to obtain. It was considered that the measurement was biased because of the high volatility of the test item. Thus the measurement was performed using sealed crucibles. Three successive tests were retained.
Mean onset for boiling occurred at 224.3°C ± 0.3 °C. The validity criteria were fulfilled: the standard deviation within the three replicate assessments did not exceed 0.5 °C.
Description of key information
Experimental boiling point = 224.3°C (atmP assumed slightly > 1 atm).
QSAR estimation = 232.8°C
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 224.3 °C
Additional information
A reliable experimental study, conducted according to a recognized EC method and under GLP, is available. Despite restrictions due to test conditions and incomplete test item identification, it is considered as key study, and the result is retained as key data.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
