Results
No melting was observed. Following observations were made:
- 350 °C strong colour change
- 410 °C lower side becomes darker
- 437 °C substance changes to intensive yellow
- 450 °C substance changes to pale okker
- 456 °C substance changes increasingly (brownish)
- 466 °C substance changes to brown
- 498 °C substance becomes darker, no melting
Description of key information
The test item has no melting point up to 500 °C, the decomposition starts at 350 °C.
Key value for chemical safety assessment
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.
