- >= 218 - <= 232 °C
- Decomposition:
- yes
- Decomp. temp.:
- >= 208 - <= 240 °C
Any other information on results incl. tables
Three measurements were performed: on each measure, the same normal behaviour of the sample was observed. The mean of the three determination range was the following:
208°C: the sample began a decomposition changing colour to light brown
214°C: in the sample dark splashes appeared
218°C: the dark splashes began to generate bubbles and the solid sample started to melt transition with an apparent decomposition
220°C: the sample continued the decomposition changing colour to red
232°C: the sample was completely red and melted
240°C: the sample remained liquid and changed its colour to dark brown
Applicant's summary and conclusion
- Conclusions:
- The melting point ranges between 218 to 232 °C .
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
