- Key result
- Remarks on result:
- not determinable
- Remarks:
- No boiling point was observed in the range from 25 °C to 500 °C.
- Conclusions:
- No boiling point was observed up to 500 °C.
- Executive summary:
A study was conducted in order to determine the melting point of the test item according to OECD test guideline 102 and European Commission Regulation (EC) No. 440/2008, Method A.2. Differential scanning calorimetry (DSC) measurements were performed between 25 °C and 500 °C. The DSC measurement in an aluminium crucible with a hole showed neither an endothermal effect nor an exothermal effect in the temperature range of 25 - 500 °C. After the measurement the test item was unchanged, and no mass loss was observed. Therefore, it was concluded that the test item had no boiling point at atmospheric conditions up to 500 °C.
Reference
The DSC measurement in an aluminium crucible with a hole showed neither an endothermal effect nor an exothermal effect in the temperature range of 25 - 500 °C. After the measurement the test item was unchanged, and no mass loss was observed. Under consideration of the result from the DSC measurement it was concluded that the test item had no melting point and no boiling point at atmospheric conditions up to 500 °C.
Description of key information
No boiling point was observed up to 500 °C.
Key value for chemical safety assessment
