Parameter:
other: Thermal stability via DSC measurement.
Remarks on result:
other: The heat of decomposition was < 500 J/g. The main test on explosive properties was not required.

Results
Thermal Stability
An endothermal effect in the temperature range 80 to 160 °C was seen, no exothermal effects were found within that range. The measurement was terminated at 500 °C, after that a black residue was seen in the crucible.

A 2nd DSC measurement showed an endothermal effect in the temperature range 95 to 165 °C and no exothermal effects. The measurement was terminated at 500 °C, after that a black residue was seen in the crucible. Results are summarized in Table 1.

Explosive Properties
The heat of decomposition was below 500 J/g, therefore the main test on explosive properties was not necessary.

Conclusion: The test item had no explosive properties.

 

Description of key information

Not explosive (EU Method A.14., Thermal Stability)

Key value for chemical safety assessment

Explosiveness:
non explosive

Additional information

Heat of decomposition determined by Differential Scanning Calorimetry was below 500 J/g. Main test on explosive properties not necessary.

Justification for classification or non-classification

The available data on explosive properties of the test substance do not meet the criteria for classification according to Regulation (EC) 1272/2008, and are therefore conclusive but not sufficient for classification: The exothermic decomposition energy is less than 500 J/g.
