Administrative data
Link to relevant study record(s)
- Endpoint:
- boiling point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 15 May 2003
- 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:
- yes
- Type of method:
- differential scanning calorimetry
- Decomposition:
- yes
- Decomp. temp.:
- > 290 °C
- Remarks on result:
- other: The test substance decomposes before boiling
- Conclusions:
- Under the conditions of the test, the test material was found to decompose before boiling. Decomposition was found to occur at temperatures above 290 °C. The study is considered to be reliable, relevant and adequate for risk assessment purposes.
- Executive summary:
The boiling point and decomposition of the test material was determined in accordance with the standardised guideline EU Method A.2 using differential scanning calorimetry. Under the conditions of the test, the test material was found to decompose before boiling. Decomposition was found to occur at temperatures above 290 °C.
Reference
Initially two samples of approximately 8-10 mg of test material were heated in crucibles at 10 K/minute from 25-450 °C under 75 mL/min air purge and a 75 mL/min nitrogen purge.
All scans showed endothermic behaviour with a small peak at 150 °C, followed by a large endotherm with an onset of ca. 190 °C. All four scans gave a broad endothermic peak with an onset of 290 °C followed by some endothermic and exothermic activity. This may be indicative of decomposition with no definitive boiling point. This is further substantiated by the significant amount of weight loss (70-90 %) and the formation of dark brown oil.
The small endothermic peak at 150 °C is likely to be some solid-state change and the large endothermic peak at ca. 190 °C is the melting point. No definitive boiling point peak was observed and the test substance appears to decompose at temperature above 290 °C without boiling.
Description of key information
Decomposes before boiling, thus no boiling point could be determined; decomposition commences at 290 °C, EU Method A.2, Differential Scanning Calorimetry, Das 2003
Key value for chemical safety assessment
Additional information
The boiling point and decomposition of the test material was determined in accordance with the standardised guideline EU Method A.2 using differential scanning calorimetry. Under the conditions of the test, the test material was found to decompose before boiling. Decomposition was found to occur at temperatures above 290 °C.
The study was performed in line with GLP and an accepted standardised guideline with a high standard of reporting. The study was assigned a reliability score of Klimisch 1 and considered suitable for assessment as an accurate reflection of the test substance.
The available data are considered to be complete and the result determined, the test substance decomposes before boiling (decomposition commences at 290 °C), was carried forward for risk assessment.
