PRELIMINARY TEST WITH TGA
From 225°C upwards the weight of the sample decreased significantly. At 281°C, the sample weight had decreased by 25%. After the experiment it was observed that the test substance was evaporated from the sample container.
DSC EXPERIMENTS
- Experiment 1: During cooling no clear effects were observed which were due to crystallization of the test substance. During heating a glass transition was observed between -75°C and -25°C. The inflection point of the glass transition was -59.43°C. An endothermic peak between 225°C and 325°C was observed. The extrapolated onset temperature of the peak was 288.52°C. The effect was most likely obtained due to evaporation of the test substance. After the experiment it was observed that the test substance was evaporated from the sample container.
- Experiment 2: To investigate the evaporation peak a closed sample container was applied in Experiment 2. The extrapolated onset temperature of the evaporation peak was 350.48°C. The endothermic peak shifted to higher temperatures. It demonstrated that evaporation of the test substance was the reason for the endothermic effect. After the experiment it was observed that the test substance was evaporated from the sample container.
- Experiment 3: Similar results as with Experiment 1 were obtained. The inflection point of the glass transition was -59.44°C. The extrapolated onset of the evaporation peak was 288.46°C. After the experiment it was observed that the test substance was evaporated from the sample container.
The melting temperature (glass transition) was determined as the average melting temperature obtained from experiment 1 (-59.43°C) and experiment 3 (-59.44°C).
VISUAL OBSERVATION
After 20.25 hours at -22.0 ± 0.2°C the sample was a viscous liquid. After 20.25 hours at -81.4 ± 1.8°C the sample was a solid. Based on this, it was concluded that the melting temperature of the test substance is between -81°C and -22°C.
TGA/DSC curves: see attached document.
Applicant's summary and conclusion
- Conclusions:
- The melting temperature (glass transition) of the substance has been determined to be -59°C using differential scanning calorimetry (GLP-compliant study in accordance with EC A.1, OECD 102 and EPA OPPTS 830.7200).
