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 November 2006
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 103 (Boiling point/boiling range)
- Version / remarks:
- (1995)
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.2 (Boiling Temperature)
- Version / remarks:
- (1992)
- Principles of method if other than guideline:
- In addition to the experimental test, a theoretical boiling point was calculated from the structural formula using the software MPBP.WIN v1.41 by the Environmental Protection Agency (adapted Stein and Brown method).
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- photocell detection
- Key result
- Decomposition:
- yes
- Decomp. temp.:
- >= 103.3 °C
- Boiling pt.:
- 320.81 °C
- Remarks on result:
- other: calculation according to method of EPA (adapted Stein and Brown method)
- Conclusions:
- The test item has no boiling point up to a temperature of 103.3°C (103 kPa) as determined by photocell detection in accordance to Regulation EC No. 440/2008 Method A.2.and OECD Test Guideline 103 (1995).
The test item showed decomposition starting at 103.3°C. A change in colour from colourless to deep yellow was observed. Calculation of the boiling point, based on the EPA method, gave a value of 320.8°C. The experimental observations showed, however, that the test item was not stable when heated. Therefore, the calculated value was considered as not relevant under practical conditions.

Description of key information
Decomposition started at 103.3°C. No boiling point could be determined up to 103.3 °C.
Method: OECD Test Guideline 103 (1995) and EC Method A.2.(1992),(photocell detection)
Key value for chemical safety assessment
Additional information
The test item has no boiling point up to a temperature of 103.3°C at (103 KPa). The test item showed signs of decomposition starting at 103.3°C. A change in colour from colourless to deep yellow was observed.
