- yes (incl. QA statement)
- Type of method:
- differential scanning calorimetry
- Specific details on test material used for the study:
- Test Item was used in its initial form.
- Remarks on result:
- not determinable
- Conclusions:

- Executive summary:
The thermal behaviour of the substance was investigated using the Differential Scanning Calorimetry method, according to the OECD guideline 103. A small amount of test item was weighed into a one-way 40 µl aluminum crucible and sealed with pierced aluminum lid using a capsule presser. Thus prepared capsule was inserted into the furnace of the DSC device.
The sample was investigated heating from room temperature to 500 °C with 10 °C/min heating rate. As reference sample an empty crucible of the same type was used. The heat flow and any thermal events were recorded, as well as the onsets and the related energies. Before and after the test, the weight and the appearance of the sample were determined. The measurement was performed under nitrogen atmosphere. The experiment was performed in duplicate.
The evaluation of the data was performed using the software STARe. As result, a thermogram was obtained in which the heat flow of the investigated sample is given as a function of the temperature. By integrating the area under the heat flow signals, the enthalpy of the process was obtained.
Before the test the appearance of the test item was yellow liquid. After the experiments the test item became black, porous and its volume increased in the crucible.
An endothermic reaction was determined in the range of 84.5 – 121.0 °C (357.6 – 394.2 K), in part associated with the boiling of the water.
During the heating phase the test item showed an endothermic signal in the temperature range of approx. 60 - 130 °C that can be in part associated with the boiling of the water; it could be reasonable to expect that also part of the organic matter can be involved by transformation and/or decomposition. However, due to the composition of the substance, a boiling cannot be precisely determined.
Conclusion
An endothermic reaction was determined in the range of 84.5 – 121.0 °C (357.6 – 394.2 K), in part associated with the boiling of the water. Based on the appearance of test item after the tests, it is concluded the test item decomposes below 500 °C.
Reference
Before the test the appearance of the test item was yellow liquid. After the experiments the test item became black, porous and its volume increased in the crucible.

Description of key information
Not determinable; an endothermic reaction was determined in the range of 84.5 – 121.0 °C (357.6 – 394.2 K), in part associated with the boiling of the water. Based on the appearance of test item after the tests, it is concluded the test item decomposes below 500 °C.
Key value for chemical safety assessment
