- Endpoint:
- boiling point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 6-10.9.2012
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- comparable to guideline study
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- EU Method A.2 (Boiling Temperature)
- Deviations:
- no
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- OECD Guideline 103 (Boiling Point)
- Deviations:
- no
- GLP compliance:
- no
- Type of method:
- differential scanning calorimetry
- Key result
- Atm. press.:
- 101.325 kPa
- Decomposition:
- yes
- Decomp. temp.:
- 210 °C
- Conclusions:
- Under the conditions of this study, the boiling temperature of the test substance could not be determined because of thermal decomposition of the sample.
- Executive summary:
The boiling temperature of the test material was investigated using methodology equivalent to that outlined in the standardised guidelines OECD 103 and EU Method A.2 using Differential Scanning Calorimetry (DSC).
A DSC-curve was recorded during the experiment. A broad exothermic peak was observed between 210 and 320 °C, caused by thermal degradation of the test substance. The extrapolated onset temperature of the exothermic peak was 239.1 °C. The broad endothermic peak was observed between 490 and 520 °C. After the experiment the sample had lost 1.29 mg (81.65 %) of its mass and the residue had a black colour.
No endothermic peak corresponding to boiling temperature of the test substance was recorded in the tested temperature range from 25 to 640 °C. Thermal degradation of the test substance connection with the loss of the mass started at the temperature 210 °C.
Under the conditions of this study, the boiling temperature of the test substance could not be determined because of thermal decomposition of the sample.
