Reference
Temperature range [°C] | Onset [°C] | Peak max. [°C] | Enthalpy [J/g] | Remarks |
210 - 228 | 218 | 218 | - 131 | Melting |
246 - 315 | 266 | 295 | 242 | Decomposition |
316 - 355 | 328 | 343 | 123 | Decompostion |
The DSC measurement shows no endothermic effects between the melting point and the decomposition starting at 246 °C. Due to this the test item has no boiling point at atmospheric pressure.
Description of key information
The technical substance has no boiling point at atmospheric conditions because it decomposes at temperatures between 246 °C and 355 °C.
(OECD Guideline 103, DSC)
Key value for chemical safety assessment
- Temperature of decomposition (state purity):
- 246 °C
Additional information
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.
