Any other information on results incl. tables

In the TGA test, a sample of the test item was heated from 30 °C to 675 °C in an inert gas atmosphere (N2). Between 30 °C and 150 °C (starting point of decomposition according to the visual observations), it lost 1.1 % of its weight. Above 150 °C (onset), the weight continuously decreased and reached a loss of approx. 91 % at 600 °C. During the first heating period of the main DSC test, an endothermic signal was recorded at around 50.2 °C (peak top temperature). No additional phase transition could be observed up to 150 °C. Thus, no boiling point/range could be identified; the test item decomposes above 150 °C.

Applicant's summary and conclusion

Conclusions:

No boiling point could be determined. Decomposition of the substance started at temperatures above 150 °C.

Executive summary:

Determination of the boiling point was was carried out according to OECD Guideline 103. Thermogravimetry (TGA) and Differential Scanning Calometry (DSC) were employed. In the TGA test, a sample of the test item was heated from 30 °C to 675 °C in an inert gas atmosphere (N2). Between 30 °C and 150 °C (starting point of decomposition according to the visual observations), it lost 1.1 % of its weight. Above 150 °C (onset), the weight continuously decreased and reached a loss of approx. 91 % at 600 °C. During the first heating period of the main DSC test, an endothermic signal was recorded at around 50.2 °C (peak top temperature). No additional phase transition could be observed up to 150 °C. Thus, no boiling point/range could be identified; the test item decomposes above 150 °C.
