Preliminary Test
Starting at 325°C, the weight of the sample decreased significantly. At 385°C, the sample weight had decreased by 25%.After the experiment, a black charred residue remained in the sample container (original colour: off white). The change of the colour indicated reaction and/or decomposition of the test item.
Main Study
An endothermic peak was observed between 25°C and 150°C. The
endothermic effect was most likely obtained due to the evaporation of
impurities. An endothermic effect was observed between 200°C
- 250°C followed by an endothermic effect starting at
300°C. The endothermic effect between
200°C - 250°C was most likely
obtained due to melting of the test item. The endothermic effect
starting at 300°C was probably obtained due to reaction and/or
decomposition of the test item.
After the experiment, a brown charred residue remained in the sample container (original colour: off white). The change of the colour indicated reaction and/or decomposition of the test item.
In order to investigate the endothermic peak between 25°C and 150°C, Experiment 2 was stopped directly after the peak. After the experiment, residue was unchanged. It demonstrated that evaporation of impurities was the reason for the endothermic effect.
In order to investigate the melting peak, Experiment 3 was stopped directly after the melting peak. After the experiment, a light yellow residue remained in the sample container (original colour: off white). The change of the colour indicated reaction and/or decomposition of the test item and not melting.
Applicant's summary and conclusion
- Conclusions:
- The melting and boiling temperature of V182675 were tested by DSC.
Reaction and/or decomposition of the test item was observed during DSC experiments at temperatures of > 175°C (> 448K). Melting and/or boiling of the test item was not observed below the temperature at which reaction and/or decomposition started. Based on this, the test item has no melting and/or boiling temperature.
