In the preliminary test, the weight of the sample decreased significantly at 400°C. After the experiment, a brown/black molten residue remained in the sample container (original colour: off-white). The change of colour indicated reaction and/or decomposition of the test item.

In the DSC experiments, a small endothermic effect (i.e slight bending of the line) was observed at 375°C. After the experiment, a dark orange/brown molten residue remained in the sample container (orignal colour: off-white). The change of the colour indicated reaction and/or decomposition of the test item.

Conclusions:
The test item start to decompose at 375°C before boiling.
Executive summary:

The boiling point of test item was determined by the differential scanning method according to recognised guideline and in compliance with GLP (Brekelmans, 2018). No deviation from the guideline was observed in the study.

The boiling point was determined in two assays. The test item startw to decompose at 375°C before boiling and no boiling point could be identified.

Description of key information

The boiling point of the test item was detemined in a key study of Klimisch validity 1 performed according to recognised guidelines and in compliance with GLP (Brekelmans, 2018).

No deviation from the guideline was observed in the study.

Key value for chemical safety assessment

Additional information

No boiling point could be determined. Indeed, the test item decomposed before boiling. The decomposition start at 375°C.
