Any other information on results incl. tables

Two DSC measurements in aluminium crucibles with a hole showed showed an exothermal effect after the melting starting at approx. 100 °C. The mass loss after the DSC measurements amounted to 87%.


 The results of the DSC measurements are summarized in the table below:

Applicant's summary and conclusion

Conclusions:
The test item had no boiling point under atmospheric conditions. Decomposition started at approximately 100 °C
Executive summary:

Test Design: The boiling point/range is determined by differential scanning calorimetry (DSC). The test item and the reference item are heated up from the starting temperature to the final temperature at a constant heating rate in a defined atmosphere (nitrogen). Open crucibles are used as containers for the test item and as empty reference crucible. The quantity of heat absorbed or released is measured and recorded.


Result: The test item had no boiling point under atmospheric conditions. Decomposition started at approximately 100 °C.
