Results and discussion
Melting / freezing point
- Decomposition:
- yes
- Decomp. temp.:
- ca. 300 °C
Any other information on results incl. tables
There was no melting point before the degradation of test item (at approximately 300°C an apparent decomposition was observed, the light yellow powder became brown). Therefore, the melting point (or melting range) of the test item was not determined.
Applicant's summary and conclusion
- Conclusions:
- There was no melting point before the degradation of test item (at approximately 300°C an apparent decomposition was observed, the light yellow powder became brown). Therefore, the melting point (or melting range) of the test item was not determined.
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.
