- Key result
- Boiling pt.:
- 273 °C
- Atm. press.:
- 1 013 hPa
- Decomposition:
- ambiguous
- Decomp. temp.:
- 273 °C
- Remarks on result:
- other: mean of (271 °C; 274 °C; 274 °C)
- Conclusions:
- Under the study conditions, the test substance shows a boiling and/or thermal decomposition earliest at ca. 273 °C.
- Executive summary:
A study was conducted to determine the boiling point of the test substance according to OECD Guideline 103 and EU Method A.2. Under the study conditions, the test substance shows a boiling and/or thermal decomposition earliest at ca. 273 °C (Kintrup, 2017).
Reference
From 273 °C the test substance shows a boiling and/or thermal decomposition with evaporation of decomposition components. The DCS measurements were confirmed with TGA measurements under the same conditions. The start of the area of boiling temperatures is defined by using the on-set temperature.
Description of key information
The boiling point was determined according to OECD Guideline 103 and EU Method A.2 (Kintrup, 2017).
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 273 °C
Additional information
boiling and/or thermal decomposition at ca. 273 °C
