- Executive summary:
Method:
Decomposition was determined by means of Differential Scanning Calorimetry according to the guideline OECD 102 corresponding to the internal method SOP-STR 028.
Observation:
Endothermic effect was observed between 167 and 214 °C (onset = 195 °C; enthalpy = -8.4 J/g). Release of imbibition solvent was observed between 25 and 150 °C. Exothermic effect was observed between 250 -345 °C (onset = 273 °C; enthalpy = -79.3 J/g).
Results:
Decomposition of the tested substance follow the exothermic effect. Decomposition was observed at a temperature > 345°C
Reference
Endothermic effect: 167 -214 °C (onset = 195 °C; enthalpy = -8.4 J/g).
Release imbibition solvent: 25-150 °C.
Exothermic effect: 250 -345 °C (onset = 273 °C; enthalpy = -79.3 J/g).
Decomposition: > 345 °C.
Description of key information
Decomposition > 345 °C
Key value for chemical safety assessment
Additional information
Decomposition was determined by means of Differential Scanning Calorimetry according to the guideline OECD 102 corresponding to the internal method SOP-STR 028.
The tested substance decomposes before melting at a temperature > 345 °C.
