Method
The test was performed according to internationally accepted testing procedures, using the Differential Scanning Calorimetry method for the analysis.
Result
Between 134 -164 °C (onset at 150.24 °C; enthalpy = -26.9 J/g) there is a first endothermic peak, between 203 - 256 °C (onset at 212.98 °C; enthalpy = -34.12 J/g) there is a second endothermic peak followed by a degradation starting at 290 °C
Reference
Between 134 -164 °C (onset at 150.24 °C; enthalpy = -26.9 J/g) there is a endothermic peak associated to the release of water/ solvent, between 203 - 256 °C (onset at 212.98 °C; enthalpy = -34.12 J/g) there is a endothermic peak related to the melting of test item, followed by a degradation starting at 290 °C.
Description of key information
The substance decomposes starting from 290 °C.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 212.98 °C
Additional information
The Melting Point analysis was performed according to internationally accepted testing procedures, using the Differential Scanning Calorimetry (DSC) method for the analysis.
Between 134 -164 °C (onset at 150.24 °C; enthalpy = -26.9 J/g) there is a first endothermic peak, between 203 - 256 °C (onset at 212.98 °C; enthalpy = -34.12 J/g) there is a second endothermic peak followed by a degradation starting at 290 °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).
