EC number: 603-316-2 | CAS number: 129050-27-7
From the TGA curve it could be derived that the weight of the sample decreased significantly at 250°C. At 314°C the sample weight has decreased by 25%. After the experiment, a black molten 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 100°C and 150°C. The extrapolated onset temperature of the peak was 116.130°C. The effect was most likely obtained due to melting. A second endothermic peak was observed starting at 250°C due to reaction and/or decomposition of the test item. After the experiment, a beige molten residue remained. To investigate the melting peak between 100°C and 150°C, a repeated heating cycle was applied. The extrapolated onset temperature of the melting peak was 116.189°C. The melting temperature of T001592 was determined as the average melting temperature obtained from Experiment 1 and Experiment 2 and equals 116.2°C (389.3K).
