Reference
Melting point / melting range: DSC measurement
Two DSC measurements with a heating rate of 10 K/min showed a wide range endothermal effect in the temperature range of 50 – 240 °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.

An additional measurement with the capillary method was performed in order to clarify the melting range.
Melting point / melting range: capillary tube in a metal block
A measurement with the capillary method was performed to clarify the results of the DSC measurements. Since this measurement was performed only as a verifying screening a high heating rate of 10 K/min was chosen and therefore the absolute temperature values derived with the capillary method are not as accurate as the DSC results. The filling height of the test item was approximately 5 mm. The results are summarized in Table 2.

Under consideration of the results from the DSC measurements, the capillary method and the visual inspection after the measurement it was concluded that the test item had no melting point at atmospheric conditions.
Description of key information
