TGA EXPERIMENT (PRELIMINARY TEST)
Starting at 150°C, the weight of the sample decreased significantly: 25% weight loss at 374°C and 70% weight loss at 426°C.
After the experiment, a dark brown molten residue remained in the sample container. The change of the colour indicated reaction and/or decomposition of the test item.
DSC EXPERIMENT 1
During cooling two exothermic peaks were observed between 0°C and -50°C, mostly likely due to crystallisation. During heating an endothermic peak was observed between -50°C and 25°C (extrapolated onset temperature: -19.707°C). Another endothermic peak was observed between 25°C and 75°C (extrapolated onset temperature: 51.062°C). The endothermic effects were most likely obtained due to melting of the test item. Up to the maximum temperature of 374°C, no signal associated with boiling was observed. After the experiment, a yellow molten residue remained in the sample container. The colour of this residue was darker than before DSC analysis. It was, therefore, concluded that the test item had reacted and/or decomposed during the test.
DSC EXPERIMENT 2
In order to investigate whether reaction and/or decomposition of the test item did already occur during melting, Experiment 2 was stopped directly after the second melting peak. The extrapolated onset temperature of the first peak was -20.071°C and of the second peak was 50.169°C. After the experiment, a light yellow molten residue remained in the sample container. The colour of this residue agreed with the colour before DSC analysis. This demonstrated that melting was the reason for these two endothermic effects and that reaction and/or decomposition of the test item did not occur at temperatures up to 65°C.
DATA HANDLING
The melting temperature was determined as a melting range obtained from the average extrapolated onset of the first melting temperature (-19.9°C) and the average peak maximum of the last melting temperature (50.6°C).
Applicant's summary and conclusion
- Conclusions:
- The melting range of the substance was determined to be -19.9 to 50.6°C.
- Executive summary:
Differential Scanning Calorimetry (DSC) experiments were performed in a GLP study according to EC A.1, OECD 102 and OPPTS 830.7200.
A melting range instead of a well defined melting temperature was determined. From duplicate experiments, the melting range was determined to be -19.9°C to 50.6°C.
Reaction and/or decomposition of the substance occurs at temperatures above 65°C.
