Results and discussion
Melting / freezing point
- Key result
- Melting / freezing pt.:
- 216 °C
- Atm. press.:
- ca. 1 013 hPa
- Decomposition:
- yes
- Decomp. temp.:
- 216 °C
Applicant's summary and conclusion
- Conclusions:
- The test item started to melt at 216°C (ca. 1013 hPa) under decomposition.
- Executive summary:
The melting point of the test item was investigated using DSC. In the DSC run, the onset temperature (melting point/decomposition) was determined to be 216°C at ca. 1013 hPa (no further thermic effects were observed up to this temperature).
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).
