From the TGA curve it could be derived that the weight of the sample decreased significantly at 283°C. At 291°C the sample weight has decreased by 70%. After the experiment, a colorless residue remained in the sample container (original colour: white). The change of the colour indicated reaction and/or decomposition of the test item.
In order to determine the melting more precisely, the DSC curve with a heating rate of 20°C/min was obtained and showed an endothermic peak between 25°C and 75°C. The extrapolated onset point was 54.174°C. The effect was most likely obtained due to melting of the test item. After the experiment it was observed that the test item was evaporated from the sample container.
Similar results were obtained in a further experiment. The extrapolated onset of the melting peak was 54.552°C. The extrapolated onset of the evaporation peak was 285.792°C. After the experiment it was observed that the test item was evaporated from the sample container.
To investigate the endothermic peak between 25°C and 75°C, the temperature program of experiment 3 was stopped after the endothermic effect. The extrapolated onset temperature of the melting peak was 54.895°C. After the experiment, a colorless molten residue remained in the sample container. The observation demonstrated that the endothermic effect was due to melting of the test item.
The melting temperature of T001597 was determined as the average melting temperature obtained from Experiment 1, Experiment 2 and Experiment 3 and equals 54.5°C (327.7K).
