- 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:
Esothermic effect was observed between 272 and 405 °C (onset = 257.4°C; enthalpy = 40.8 J/g and onset = 325.9°C; enthalpy = 64.0 J/g). Release of imbibition solvent was observed between 25 and 140 °C
Results:
Decomposition of the tested substance was observed between 272 and 405 °C (onset = 257.4°C; enthalpy = 40.8 J/g and onset = 325.9°C; enthalpy = 64.0 J/g).
