Remarks on result:
other: ONSET-temperatures

DTA:

At an oven temperature of 144 °C a exothermic reaction took place.

DSC:

Decomposition heat 596 -664 J/g

Conclusions:
The substance decomposes with an ONSET-temperature of 155-168 °C.

Description of key information

No melting point is derived. The substance decomposes at about 160 °C. For the chemical safety assessment, a value of 160 °C was assumed.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
160 °C
