Reference
Preliminary Tests
The DSC·curve of the preliminary test (heating rate of 20°C/min from 25 °C to 400 °C) is shown in Figure 1 of the report. An endothermic heat effect, the melting, was observed starting at 236.7 °C followed by an exothermic reaction starting at about 250 °C After the experiment, the sample had lost about 33% of its mass and a black shiny residue remained.
Main Tests
Melting Point / Melting Range
In order to determine the melting more precisely, further DSC·runs were recorded between 180 °C and 260 °C with a heating rate of 5°C/min. In the first main test run, the melting was observed at 233.2 °C, during the second main test run at 233.5 °C. During these runs, the sample lost about 6 % of its weight each and a red to black shiny melt remained.
