- Procedure
Thermal Stability: Differential Scanning Calorimetry
The thermal stability was determined by differential scanning calorimetry (DSC). The test item and the standard material (aluminium oxide) were heated up from ambient temperature to the final temperature (250 °C) at a constant heating rate (3 K/min) in a defined atmosphere (nitrogen). Closed glass crucibles were used as containers for the test item and the standard material. The quantity of heat absorbed or released was measured and recorded. Approx. 10 mg of the test item were used.
Melting Point / Melting Rang, Boiling Point / Boiling Range: Differential Scanning Calorimetry
The determination of the melting point / boiling point was carried out by differential scanning calorimetry (DSC). The test item was heated up from the starting temperature (-100 °C, -20 °C and 10 °C, respectively) to the final temperature (300 and 450 °C, respectively) at a constant heating rate (10 K/min) in a defined atmosphere (nitrogen). The quantity of heat absorbed or released was measured and recorded. Aluminium crucibles with a small hole were used as containers for the test item and as empty reference crucible. About 11 mg to 19 mg of the test item were used. - GLP compliance:

The test item has no melting point above -100 °C under atmospheric conditions. Possibly a melting point could not be determined due to the large number of substances of which the test item is assembled.
Applicant's summary and conclusion
- Conclusions:
- The test item has no melting point above -100 °C under atmospheric conditions.
- Executive summary:
The test item has no melting point above -100 °C under atmospheric conditions.
