Referenceopen allclose all
The heating run showed melting of a minor crystalline component starting at around 14 °C. The main crystalline components melted between 39 - 96 °C.
Using a linear heating rate of 0.5°C/min from 190°C, the test item turned a brown colour at about 195°C and then turned black at about 215°C without completely melting. Hence, 195°C is considered as the decomposition temperature.
Description of key information
In the key study the test item decomposed prior to melting, starting at 195°C
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 195 °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.
