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:
- 1999/08/25 to 1999/09/22
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- comparable to guideline study
- Qualifier:
- according to guideline
- Guideline:
- EPA OPPTS 830.7220 (Boiling Point / Boiling Range)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.2 (Boiling Temperature)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 103 (Boiling Point)
- Deviations:
- yes
- Remarks:
- See comment bellow in "Principles of method if other than guideline"
- Principles of method if other than guideline:
- Due to thermal decomposition of the test substance at a temperature lower than that of the boiling point, it was not possible to determine the boiling point at normal pressure. Additional investigation of thermal behavior, using differential scanning calorimetry, were perfomend.
- GLP compliance:
- yes
- Type of method:
- method according to Siwoloboff
- Key result
- Decomposition:
- yes
- Remarks on result:
- not determinable
- Remarks:
- No evidence of boiling.
- Conclusions:
- Determination of boiling point is not possible.
- Executive summary:
The boiling point of the test substance has been determined using differential scanning calorimetry. The study was perfomed in accordance with OECD Guideline 103, EU Method A.2 and EPA OPPTS 830.7220. The differential scanning calorimetry indicated that the test substance decomposes oxidatively in air immediately after melting. Determination of boiling point is not possible.
