Method:
The study was performed according to OECD Guidelines 102 and 103, corresponding to 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). Decomposition of the tested substance follow the exothermic effect. Decomposition was observed at a temperature > 345 °C.
Results:
The substance is a powder at 20 °C (1013 hPa)
