Melting / freezing pt.:
> 300 °C
Atm. press.:
ca. 1 atm
Decomposition:
yes
Decomp. temp.:
ca. 334.28 °C
Remarks on result:
not determinable

Between 25 -140°C water evaporation occurs, followed by substance decomposition between 278 -410°C. The decomposition onset is 334.28°C with an enthalpy energy equal to 264.35 J/g.

Conclusions:
The substace melting point was determined by DSC according to OECD 102. The decomposition of the substance was observed with onset temperature equal to 334.28°C.
Executive summary:

The substance melting point was tested by thermoanalysis (DSC) according to OECD 102.

Between 25 -140°C water evaporation occurs, followed by substance decomposition between 278 -410°C. The decomposition onset is 334.28°C with an enthalpy energy equal to 264.35 J/g.

Description of key information

The test item does not melt up to 334.28°C, where decomposition starts

Key value for chemical safety assessment

Additional information

The melting point of the substance was tested by thermoanalysis (DSC) according to OECD 102 (REACH&Colours Kft, 2014). The decomposition onset was found to be 334.28°C with an enthalpy energy equal to 264.35J/g.
