- Atm. press.:
- 1 016 mBar
- Decomp. temp.:
- ca. 327 °C
- Conclusions:

- 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. The determination of the boiling point was carried out with the test substance by differential scanning calorimetry (i.e., DSC). Under the study conditions, the test substance showed boiling and/or thermal decomposition at ca. 327°C (at 1,016 mbar) (Kintrup, 2013).
Reference
From 327°C, the test substance showed boiling and/or thermal decomposition with evaporation of the decomposition components. The start of the area of boiling temperatures is defined by using the on-set temperature.
The DSC measurements were confirmed by means of a TGA measurement (up to 327°C the sample shows a weight loss of about 4 weight %) under
the same measuring conditions.
Description of key information
The boiling and/or thermal decomposition point was determined according to OECD Guideline 103 and EU Method A.2 (Kintrup, 2013).
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 327 °C
Additional information
The boiling and/or thermal decomposition point (at 1,016 mbar).
