- Key result
- Atm. press.:
- 101.325 kPa
- Decomposition:
- yes
- Decomp. temp.:
- ca. 250 °C
- Remarks on result:
- other: No boiling observed below decomposition temperature.
- Conclusions:
- Under the study conditions, boiling of the test substance was not observed below the temperature at which reaction or decomposition started.
- 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 test substance is a viscous liquid at room temperature. It does not crystallize upon cooling, but it forms a glassy state. On heating, the test substance transfers from the glassy state to the (supercooled) liquid state. Under the study conditions, boiling of the test substance was not observed below the temperature at which reaction or decomposition started (van der Baan-Treur, 2004).

Description of key information
The boiling point was determined according to OECD Guideline 103 and EU Method A.2 (van der Baan-Treur, 2004).
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 250 °C
Additional information
Boiling of the test substance was not observed below the temperature at which reaction or decomposition started (i.e. between 250°C-251°C).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
