Results

DSC measurements with a heating rate of 10 K/min showed an endothermal effect in the temperature range of 90 – 210 °C followed by exothermal decomposition above 250°C.

The results of the DSC measurements are summarized in Table 1.

Under consideration of the result from the DSC measurement and the visual inspection of the test item after the measurement, which was stopped before the exothermal decomposition, it was concluded that the test item had no melting point and no boiling point at atmospheric conditions. Decomposition started at approx. 250 °C.

Executive summary:

The test item had no melting point and no boiling point at atmospheric conditions. Decomposition started at approx. 250 °C.

Description of key information
