As a preliminary measuring for determining the thermal stability of the test substance a DSC was performed in a closed glass pan.The measurement in a closed glass pan shows an endothermic effect (melting) in the range 65-90 °C, with an onset of 79 °C and an exothermal decomposition in the range 170-220 °C, with a decomposition energy of 171 J/g.

Conclusions:
The test substance shows a mean melting point of 78 °C.
Executive summary:

The test substance shows a mean melting point of 78 °C determined in a study according to EU Method A.1.

Description of key information

The test substance shows a mean melting point of 78 °C.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
