Results and discussion

Melting / freezing point
Melting / freezing pt.:
257 °C
Decomposition:
yes
Decomp. temp.:
261 °C

Any other information on results incl. tables

The DTA shows an endothermal reaction with an onset at 256.53 °C (rounded value of 257 °C taken as melting point) and a peak at 257.94 °C.

Decomposition starts from the melting substance. The (exothermal) decomposition reaction shows an onset at 260.66 °C (rounded value of 261 °C taken as decomposition temperature) and a peak at 291.29 °C, the reaction energy of the decomposition being 1100 J/g.

Applicant's summary and conclusion

Conclusions:
Decomposition starts from the melting substance, with a melting point of 257 °C and a decomposition temperature of 261 °C.
Executive summary:

The DTA shows decomposition from the melting substance starting at 261 °C with a melting point of 257 °C.
