Any other information on results incl. tables

The substance was tested by Differential-Scanning-Calorimetry (DSC). With a heating rate of 5 K/min it shows an exothermal decomposition at a temperatur of ca. 214°C.

In a second test the substance was heated in an autoclav beginning at 60°C with a heating rate of 0.5 K/min. Under this conditions a strong decomposition is observed beginning at ca. 160°C.

Applicant's summary and conclusion

Conclusions:
The substance decomposes spontaneously above a temperature of 160 ° C.
