Results and discussion
Melting / freezing point
- Melting / freezing pt.:
- ca. 67 °C
- Decomposition:
- yes
- Decomp. temp.:
- > 180 °C
- Remarks on result:
- other: Pressure not given.
Any other information on results incl. tables
The DSC measurement showed an endothermic effect with an onset of about 67 °C, taken as melting point.
No endothermal effect other than the one referred to as melting was detected up to a temperature of ca. 180 °C. At >180 °C an exothermal effect indicates the reaction of the test item with air. As the residual test item in the crucibles was dark brown/black, the authors conclude that decomposition took place.
Applicant's summary and conclusion
- Conclusions:
- The test item has a melting point of 67 °C.
- Executive summary:
The melting point of the test substance was determined by Differential Scanning Calorimetry (DSC). The test item has a melting point of
67 °C.
