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 190 – 225 °C. The onset temperature (see Table 1) 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.
Table 1: Melting point (DSC measurements)
| Ident No. | Test item /mg | Starting temperature /°C | Final test temperature /°C | Temperature range (endothermal) /°C | Onset (melting) / °C | Crucible | Observations after the measurement |
| 38673 | 13.55 | 25 | 500 | 190 – 225 | 206.93 | Aluminium with a hole | discoloured into black |
| 38674 | 15.34 | 25 | 250 | 190 – 225 | 206.78 | Aluminium with a hole | discoloured into a beige/brown melt, |
The test item had a mean melting point of 206.9 °C.
