Boiling Point / Boiling Range (DSC)
Four DSC measurements in aluminium crucibles with a hole showed an endothermic effect in the temperature range of 260 °C to 345 °C with an onset temperature of about 315 °C to 330 °C while the test item was heated up. The onset temperature is derived from the intersection of the tangent line with the highest slope of the endothermic peak with the baseline.
| Ident-No. | Onset / °C | Temperature range / °C | Crucible |
| 30433 | 327.5 | 280 to 340 | Aluminium with a hole |
| 30434 | 314.5 | 260 to 345 | Aluminium with a hole |
| 30439 | 328.3 | 280 to 340 | Aluminium with a hole |
30440 | 329.9 | 260 to 345 | Aluminium with a hole |
Due to the broad peaks with an untypical course for a boiling point in the DSC measurements and the observation of a black residue after the DSC measurements it can be concluded that the test item boils under decomposition starting at a temperature of 260°C. This result is in accordance with the observations made in the thermal stability DSC measurement that showed an exothermic decomposition of the test item in the temperature range of 280 – 340 °C.
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.
