Differential Scanning Calorimetry (DSC) according to the OECD Test Guidelines 102 and 103.
Results
Between 40 and 180 °C there is a release of imbibition/crystallisation water, followed by three endothermic effect: the first between 238 -259 °C (onset = 242.9 °C, enthalpy = - 0.7 J/g), the second between 259-299 °C (onset at 269.3 °C, enthalpy = -5.6 J/g) and the third between 299-353 °C (onset at 305.3 °C, enthalpy = - 38.3 J/g).
Conclusion
The test item is a solid at 1013 hPa in a range of 20 °C and 180 °C.
