Preliminary TGA
From 175°C upwards the weight of the sample decreased significantly. At 327°C, the sample weight had decreased by 25%. After the experiment, brown/black residue was observed on the lid of the sample container and a brown/black residue remained in the sample container.
DSC experiment
During the cooling, no effects were observed that could indicate crystallization of the test substance. During heating, an exothermic effect was observed starting at 150°C. The effect was due to reaction and/or decomposition of the test substance. After the experiment, a brown/orange residue remained in the sample container.
Additional experiment
After storage overnight in the freezers at -20°C and -80°C the substance was a (highly viscous) liquid. From this it was concluded that the melting temperature of the test substance is < -80°C(< 193K).
Applicant's summary and conclusion
- Conclusions:
- In a differential scanning calorimetry study, the melting temperature of the substance was determined to be < -80°C. Decomposition of the substance started at 150°C. The study was performed in accordance with EC A.1, OECD 102 and EPA OPPTS 830.7200 guidelines and according to the principles of GLP.
