Preliminary test

From 100°C upwards the weight of the sample decreased significantly. At 504°C the sample weight had decreased by 25%. After the experiment, a black residue remained in the sample container (original colour: blue). The change of the colour indicated reaction and/or decomposition of the test substance.

Main study

An endothermic effect was observed between 50°C and 250°C. This effect might be due to evaporation of minor compounds but does not derive from melting of the major compound in E-C104. Therefore, this effect was not reported as melting of the test substance. An exothermic effect was observed between 300°C and 400°C. The effect was due to reaction and/or decomposition of the test substance. After the experiment, a black residue remained in the sample container. The change of the colour indicated reaction and/or decomposition of the test substance.

Conclusions:

Reaction and/or decomposition of the test substance was observed starting at 300°C (573K). Melting of the test substance was not observed below the temperature at which reaction and/or decomposition started. Based on this, the test substance has no melting temperature.
