Executive summary:

Method

Differential Scanning Calorimetry (DSC) according to the OECD Test Guidelines 102 and 103.

Results

Between 25 and 160 °C there is a release of imbibition/crystallisation water. Between 244-423 °C it is registered an exothermic effect (onset 282.3 °C, enthalpy = 1673 J/g).

Conclusion

The test item is a solid which decomposes before melting.

Description of key information

Decomposition before melting.

Key value for chemical safety assessment

Additional information

The substance was tested according to the method described into the OECD 102 Guideline.

The substance decomposes before melting at temperature above 244 °C.
