Any other information on results incl. tables

The sample began to darken at 137.9°C, before turning black at 156.2°C. A solid black residue remained

at the end of the test (temperature taken up to 350 °C).

Applicant's summary and conclusion

Conclusions:
The substance decomposes before the melting temperature is reached. Decomposition temperature is 137.9 °C.
Executive summary:

Melting point of the dry pulverised substance was determined by capillary method. The sample began to darken at 137.9°C, before turning black at 156.2°C. The substance decomposes before the melting temperature is reached. Decomposition temperature is 137.9 °C.
