Preliminary test

From 250 °C upwards the weight of the sample decreased significantly. At 305 °C and 313 °C, the sample weight had decreased by 25% and 70 %, respectively. After the experiment it was observed that the test substance was evaporated from the sample container.

Main study (first experiment)

During cooling an exothermic peak was observed between 0°C and -20°C. The effect was obtained due to crystallization of the test substance. During heating a first endothermic peak was observed between 0°C and 50°C. The extrapolated onset temperature of the peak was 20.90°C. The effect was due to melting of the test substance. A second endothermic peak was observed between 250°C and 325°C. The extrapolated onset temperature of the peak was 305.76°C. The effect was most likely obtained due to evaporation of the test substance. After the experiment it was observed that the test substance had evaporated from the sample container.

Main study (second experiment)

Similar results as with the first experiment were obtained. The extrapolated onset of the first endothermic peak due to melting was 20.13°C and the extrapolated onset of the second endothermic peak (evaporation peak) was 305.70°C. After the experiment it was observed that the test substance had evaporated from the sample container.

Main study (third experiment)

The second endothermic peak shifted to higher temperatures. It demonstrated that boiling of the test substance was the reason for the second endothermic effect. After the experiment it was observed that the test substance had evaporated from the sample container.

Applicant's summary and conclusion

Conclusions:
The boiling temperature of the substance was determined using DSC. The boiling temperature of the substance is 306°C (579 K).
