Results and discussion

Melting / freezing point
Decomposition:
yes
Decomp. temp.:
ca. 300 °C

Any other information on results incl. tables

There was no melting point before the degradation of test item (at approximately 300°C an apparent decomposition was observed, the light yellow powder became brown). Therefore, the melting point (or melting range) of the test item was not determined.

Applicant's summary and conclusion

Conclusions:
There was no melting point before the degradation of test item (at approximately 300°C an apparent decomposition was observed, the light yellow powder became brown). Therefore, the melting point (or melting range) of the test item was not determined.
