Results and discussion
Melting / freezing point
- Decomposition:
- yes
- Remarks:
- No melting point as the test substance decomposes at 202.2 °C +/-0.5°C
- Decomp. temp.:
- ca. 202.2 °C
Any other information on results incl. tables
In three runs the tests substance did not melt, but it decomposed. At 185 to 200°C the colour of the test substance changed to brown. At 201.5°C the test substance formed drown agglomerates which moved toward the upper end of the capillaries. The space between the agglomerates was clear. At 208.5 °C most of the substance had moved out of the visible area.
The displayed values at the device for the temperature of decomposition were: 202.6°C, 201.7°C and 202.3°C.
Mean point off decomposition: 202.2°C+/-0.5
Applicant's summary and conclusion
- Conclusions:
- No melting point as the test substance decomposes at 202.2 °C +/-0.5
