Results and discussion
Melting / freezing point
- Key result
- Decomposition:
- yes
- Decomp. temp.:
- >= 198 °C
- Remarks on result:
- other:
- Remarks:
- see below
Any other information on results incl. tables
The observed onset of weight loss at 198°C indicates that the sample material is thermally unstable before melting. Observation of a dark gray powder (color change) after thermal treatment up to 750°C also indicates that the material is thermally unstable.
Applicant's summary and conclusion
- Conclusions:
- The test material decomposed upon heating, starting at 198°C, and was still under powder form up to 750°C.
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.
