Reference
In aluminium pans with a hole, there were indicated three endothermic effects, a first one in the temperature range 70 - 85 °C, a second one from 120 to 155 °C, and a third one from 175 to 205 °C. An exothermal decomposition of the test substance starts at approximately 250 °C. The test substance doesn't show any endothermic effect between the endothermic transformation process and the temperature where the exothermal decomposition begins. Thus, neither a boiling point nor a boiling range exists at atmospheric pressure.
Description of key information
> 250 °C at 1013.3 hPa (decomposition)
Key value for chemical safety assessment
Additional information
The boiling behaviour of the substance was investigated in accordance with OECD Guideline 103 and EU Method A.2 using differential scanning calorimetry. No endothermic effects were observed between the endothermic transformation process and the temperature where the exothermal decomposition began (ca. 250 °C). Therefore neither the boiling point, nor the boiling range of the substance exists at the atmospheric pressure (1013.3 hPa).
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.
