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.
