Results and discussion
Melting / freezing point
- Key result
- Decomposition:
- yes
- Decomp. temp.:
- 137.9 °C
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.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
