Key result

TGA EXPERIMENT (PRELIMINARY TEST)

- 25% weight loss at 433°C

- 70% weight loss at 471°C

After the experiment, a black brown molten residue remained in the sample container (original colour: white). The change of the colour indicated reaction and/or decomposition of the test item.

DSC EXPERIMENT 1

An endothermic peak was observed between 25°C and 100°C. The endothermic effect was most likely caused by melting of the test item.The extrapolated onset temperature was 59.722°C. An exothermic peak was observed from 200°C. The exothermic effect was probably caused by reaction and/or decomposition of the test item. After the experiment, an orange molten residue remained in the sample container (original colour: white). The change of the colour indicated reaction and/or decomposition of the test item. 

DSC EXPERIMENT 2

In order to investigate the melting peak, a second experiment was performed and the end temperature was set to stop shortly after the melting peak. The extrapolated onset temperature was 59.319°C. After the experiment, a colourless molten residue remained in the sample container (original colour: white). It demonstrated that melting was the reason for the endothermic effect.

DATA HANDLING

The melting temperature was determined as the mean melting temperature of Experiment 1 (59.722°C) and Experiment 2 (59.319°C).

TGA and DSC curves are attached as background material.

Conclusions:

The melting temperature of the substance was determined to be 59.5°C (332.7 K).

Executive summary:

Differential Scanning Calorimetry (DSC) experiments were performed in a GLP study according to EC A.1, OECD 102 and OPPTS 830.7200.

The melting temperature of the substance was determined to be 59.5°C (332.7 K).

TGA EXPERIMENT (PRELIMINARY TEST)

- 25% weight loss at 433°C

- 70% weight loss at471°C

After the experiment, a black brown molten residue remained in the sample container (original colour: white). The change of the colour indicated reaction and/or decomposition of the test item.

DSC EXPERIMENT 1

An exothermic peak was observed from 200°C. The exothermic effect was probably caused by reaction and/or decomposition of the test item.After the experiment, an orange molten residue remained in the sample container (original colour: white). The change of the colour indicated reaction and/or decomposition of the test item. 

CONCLUSION

Reaction and/or decomposition of the test itemwas observed during the DSC experiment at temperatures of > 200°C (> 473K). Boiling of the test item was not observed below the temperature at which reaction and/or decomposition started. Based on this, the test item has no boiling temperature.

TGA and DSC curves are attached as background material.

Applicant's summary and conclusion

Conclusions:

Reaction and/or decomposition of the substance was observed at temperatures > 200°C. Since boiling of the substance was not observed below the temperature at which reaction and/or decomposition started, it is concluded that the substance has no boiling temperature.

Executive summary:

Differential Scanning Calorimetry (DSC) experiments were performed in a GLP study according to EC A.2, OECD 103 and OPPTS 830.7220.

Reaction and/or decomposition of the substance was observed at temperatures > 200°C. Since boiling of the substance was not observed below the temperature at which reaction and/or decomposition started, it is concluded that the substance has no boiling temperature.
