- Conclusions:
- Thermal analysis between 25 and 450 °C in N2. The substance doesn't melt; endothermic events are seen between 51 and 141 °C and between 142 and 166 °C; decomposition starts at 271 °C.
- Executive summary:
Method
Differential Scanning Calorimetry was used to study the substance in N2. Thermal analysis was performed between 25 and 450 °C. Temperature is increased by 20 °C/min.
Results
Based on the DSC curve, loss of solvent occurs between 51 and 141 °C, followed by an endotermic event between 142 and 166 °C (onset at 146.3 °C, enthalpy at -11 J/g). Starting from 271 °C, exothermic decomposition with onset 306.6 °C and enthalpy 369.0 J/g is reported.

Key value for chemical safety assessment
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.
