Any other information on results incl. tables
Two DSC measurements in aluminium crucibles with a hole showed an endothermal effect in the temperature range of 230 - 350 °C. The onset temperature (see Table below) was derived from the intersection of the tangent line with the highest slope of the endothermal peak with the baseline. No further endothermal or exothermal effects were observed up to the final temperature (500 °C). The mass loss after the DSC measurements amounted to 100 %; however both measurements showed a few residues indicating a decomposition (see also report M-754109-01-1 linked to chapter 4.14 Explosiveness of this IUCLID dossier). The results of the DSC measurements are summarized in Table below:
| Ident No. | Test item / mg | Starting temp / °C | Final test temp / °C | Temp. range (endothermal) / °C | Onset (boiling) /°C | Crucible | Observations after the measurement |
| 39149 | 16.25 | -80 | 500 | 230 - 350 | 290.72 | Aluminium with a hole | Few grey residues, Mass loss: 100 % |
| 39154 | 17.92 | 25 | 500 | 240 - 340 | 294.59 | Aluminium with a hole | Few grey residues, Mass loss: 100 % |
The test item had a boiling range at atmospheric pressure (1013.3 hPa) of 290 - 295 °C (possibly under decomposition).
Applicant's summary and conclusion
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
