Results and discussion
Melting / freezing point
- Melting / freezing pt.:
- > 170 °C
- Decomposition:
- yes
- Decomp. temp.:
- ca. 170 °C
Any other information on results incl. tables
In the duplicate definitive determinations, the samples were observed to darken from approximately 170 deg C. At this temperature, the samples changed from a white to an off-white powder, with browning at the surface. These observations were indicative of decomposition. When taken beyond this temperature in the initial estimation, the sample formed a brown melt at approximately 210 deg C.
Applicant's summary and conclusion
- Conclusions:
- The melting point could not be determined because the test substance decomposed at temperatures above 170 deg C before melting.
- Executive summary:
Not applicable
