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:
- 2015
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.2 (Boiling Temperature)
- Deviations:
- no
- GLP compliance:
- not specified
- Type of method:
- differential scanning calorimetry
- Key result
- Decomposition:
- yes
- Decomp. temp.:
- > 360 °C
- Remarks on result:
- other: No boiling point
- Conclusions:
- No boiling point was observed since the test substance degraded above approximately 360°C (transition), with a second transition at 430°C.
- Executive summary:
A study was conducted to determine the boiling point of the test substance according to EU Method A.2. Differential scanning calorimetry (DSC) was used. Duplicate specimens of the test substance were encapsulated in aluminium pans with pierced lids and subjected to a controlled temperature program of -60°C to 500°C at 10K/min. When transition involving a change in enthalpy (endothermic in the case of boiling) occurs, that change is indicated by a departure from the base line of the temperature record. Under the study conditions, no boiling point was observed since the test substance degraded above approximately 360°C (transition), with a second transition at 430°C (Sohar, 2015).
