Applicant's summary and conclusion
- Conclusions:
- As the deviation between the two evaluated determinations was 0.5 K the result can be considered valid.
- Executive summary:
The melting point and boiling point study was determined via DSC (differential scanning calorimetry). Three DSC measurements were performed. In all measurements two endothermic peaks were detected.
In the pre-test for melting range beginning melting was observed at 143.5 °C, at 147 °C the test item was completely melted. As the pre-test was performed with a quick heating rate a measuring inaccuracy of 5 – 10 °C is plausible. Therefore the melting point under decomposition referring to the pre-test was determined under these circumstances as the first endothermic event with 138.52 ± 0.14 °C (411.67 ± 0.14 K). These values represent the mean of the first and third determination.
