Individual results
Melting point / melting range: DSC measurement
Two DSC measurements with a heating rate of 10 K/min showed an endothermal effect (melting) in the temperature range of 250 – 285 °C. The onset temperature (seeTable1) was derived from the intersection of the tangent line with the highest slope of the endothermal peak with the baseline.
The results of the DSC measurements are summarized in Table 1.
