TREATMENT OF TEST MATERIAL PRIOR TO TESTING
The sample was tested as received. No further preliminary treatment such as drying or milling was performed. - Key result
- Atm. press.:
- ca. 1 Bar
- Decomposition:
- yes
- Decomp. temp.:
- ca. 300 °C
- Conclusions:
- The boiling point of the test item could not be determined under atmospheric conditions. At approximately 300 °C decomposition of the test item started.
- Executive summary:
The boiling point/boiling range of the test item was investigated by DSC in a study conducted according to OECD 103.
The boiling point of the test item could not be determined under atmospheric conditions. At approximately 300 °C decomposition of the test item started.
Reference
Results:
One DSC measurement in aluminium crucibles with a hole showed an exothermal effect after the melting starting at approximately 300 °C. The test item had no boiling point under atmospheric conditions. Decomposition started at approx 300 °C.
