Any other information on results incl. tables
Preliminary test:
Starting at 425°C, the weight of the sample decreased significantly. At 454°C, the sample weight had decreased by 25%. After the experiment, a black charred expanded residue remained in the sample container (original colour:dark green) and a black charred residue was observed on the lid of the sample container. The change of the colour indicated reaction and/or decomposition of the substance.
Main study.
A broad endothermic effect was observed between 100°C and 300°C directly followed by an endothermic effect starting at 325°C. Based on the effect between 100°C and 300°C and the 1% weight loss during the preliminary test at the same temperatures, the first endothermic effect was most likely obtained due to the evaporation of a small part of the substance. The second endothermic effect was probably obtained due to reaction and/or decomposition of the substance. After the experiment, a dark blue/black molten residue remained in the sample container (original colour: dark green). The change of the colour indicated reaction and/or decomposition of the substance.
Applicant's summary and conclusion
- Conclusions:
- Melting of the substance was not observed below the temperature at which reaction and/or decomposition started (325 degC). Based on this, the substance has no melting temperature.
- Executive summary:
The melting temperature has been tested employing differential scanning calorimetry (DSC) according to OECD method 102, EC Guideline A.1, and OPPTS 830.7200. Reaction and/or decomposition of the substance was observed during DSC experiment starting at 325°C (598K). Melting of the substance was not observed below the temperature at which reaction and/or decomposition started. Based on this, the substance has no melting temperature.
