- Guideline:
- OECD Guideline 103 (Boiling Point)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.2 (Boiling Temperature)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- method according to Siwoloboff
- Key result
- Atm. press.:
- 1 025 mBar
- Decomposition:
- yes
- Decomp. temp.:
- > 250 °C
- Remarks on result:
- not determinable
- Conclusions:
- The boiling temperature of the test material was not determinable as the test material decomposed at temperatures above approximately 250 °C without boiling.
- Executive summary:
The boiling temperature of the test material was investigated in accordance with the standardised guidelines OECD 103 and EU Method A.2 under GLP conditions using the Siwoloboff method.
The boiling temperature of the test material was not determinable under the conditions of this study as the test material decomposed at temperatures above approximately 250 °C without boiling.
Reference
As the boiling tubes were heated at 1 °C/minute, the test material was observed to darken at temperatures above approximately 250 °C, indicating decomposition. When heating was continued beyond this temperature in a preliminary trial, the sample continued to darken when heated to 360 °C but did not boil. This was performed at a barometric pressure of 1025 mbar.
Description of key information
The boiling temperature of the test material was not determinable under the conditions of this study as the test material decomposed at temperatures above approximately 250 °C without boiling.
Key value for chemical safety assessment
Additional information
The boiling temperature of the test material was investigated in accordance with the standardised guidelines OECD 103 and EU Method A.2 under GLP conditions using the Siwoloboff method. The study was awarded a reliability score of 1 in accordance with the criteria set forth by Klimisch et al. (1997).
The boiling temperature of the test material was not determinable under the conditions of this study as the test material decomposed at temperatures above approximately 250 °C without boiling.
