- Melting / freezing pt.:
- 257 ca. °C
- Decomposition:
- yes
- Decomp. temp.:
- 261 ca. °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.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
