The onset point of the exotherm was observed to be a kinetic event dependent on the heating rate and attributed to decomposition rather than a boiling phase transition. The material was visually observed to have been converted to a black tar. This is typical for substances that undergo decomposition during DSC analysis.

Conclusions:

The decomposition range of DiBrORMA was determined to be between 359 °C and 372 °C (OECD 103).

Executive summary:

The decomposition temperature was determined by the differential scanning calorimetry (DSC). During the heating processes the material was visually observed to have been converted to a black tar. Due the difference in onset point when heating at 5 °C/minute and 10 °C/minute, the onset point was also determined to be kinetic dependent on the heating rate. The study was conducted in accordance with OECD 103 method and GLP compliant. Therefore, the study is considered reliable without restrictions.

Key result

Flash point:

> 200 °C

Atm. press.:

770 mm Hg

Test substance was brought to room temperature. The flame was introduced at 5 °C increments up to 200 °C. The preliminary test resulted in no observed flash at 200 °C. Test substance appeared to become somewhat solid, with the consistency of a fragile rubber at the completion of the experiment.

Interpretation of results:

GHS criteria not met

Conclusions:

The flash point for DiBrORMA was determined to be >200 °C (ASTM D3278).

Executive summary:

The flash point of DiBrORMA was measured using a closed cup flash point apparatus. The study was tested up to 200 °C. No flash was observed up to 200 °C. The material at the end of the experiment had become solid, with the consistency of fragile rubber. The study was conducted in accordance with guideline ASTM D3278 and was GLP compliant. Therefore, this study is considered reliable without restrictions.
