From the TGA curve it could be derived that the weight of the
sample decreased significantly at 400°C. At 422°C the sample weight has
decreased by 25%. After the experiment, a dark brown molten residue
remained in the sample container (original colour: grey brown). The
change of the colour indicated reaction and/or decomposition of the test
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 175°C and 225°C. The extrapolated onset temperature of the
peak was 197.7°C. The effect was most likely obtained due to melting. A
second endothermic peak was observed starting at 375°C due to reaction
and/or decomposition of the test item. After the experiment, a brown
molten residue remained. To investigate the melting peak between 175°C
and 225°C, a repeated heating cycle was applied. The extrapolated onset
temperature of the melting peak was 197.9°C. The melting temperature of
T001329 was determined as the average melting temperature obtained from
Experiment 1 and Experiment 2 and equals 197.8°C (471.0K).
