- Qualifier:
- according to guideline
- Guideline:
- EU Method A.2 (Boiling Temperature)
- Deviations:
- no

- no
- Type of method:

- Key result
- Decomposition:
- yes
- Decomp. temp.:
- > 150 °C
- Conclusions:
- The test item started to melt at 90 °C followed by decomposition. No boiling was observed.
- Executive summary:
The boiling point of the test substance was determined via Differential Scanning Calorimetry (DSC) and capillary tube in a metal block according to OECD 103.
For DSC, the test item was heated continously until the final temperature was reached while measureing and recording the quantity of absorbed and released heat.
For the capillary tube method, the test item was filled to a height of approx. 5 mm into the test tube and heated to the maximum temperature (410°C), while any changes of the substance are observed and recorded.
Considering the results from the thermal stability, DSC and capillary tube method, the test substance started to melt at 90°C followed by decomposition. Therefore no boiling point or range could be determined.
Reference
Under consideration of the results from the thermal stability (ambiguous onset), the DSC measurements and the capillary method it was concluded that the test item started to melt at 90 °C followed by decomposition. No boiling was observed.

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
