- Executive summary:
The boiling point of the test substance was determined using differential scanning calorimetry according to the EU Method A.2, in compliance with GLP. Under the study conditions, the boiling point of the test substance was aasessed to be 366°C at 101,700 Pa (White, 2004).
Referenceopen allclose all
A preliminary test for boiling under reduced pressure showed no boiling and no condensation up to 150°C at 14 mbar (i.e., 1400 Pa).
Therefore DSC was determined in a nitrogen atmosphere.
One preliminary test and 4 main test runs were performed resulting in a boiling range between 342.6-357.4°C (615.8-630.6 K) at 97,700 Pa.
Description of key information
Determination of the boiling point according to:
- OECD Guideline 103 and EU Method A.2 (DSC) (Tognucci, 2003)
- EU Method A.2 (DSC) (White, 2004)
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 355 °C
Additional information
- 355°C at 97,700 Pa (Tognucci, 2003)
- 366°C at 101,700 Pa (White, 2004)
