Any other information on results incl. tables

Pre-test: weight loss at 519°C 25%; at 549°C 40%

Main test: endothermic peak from 209 -275 °C followed immediately by an exothemic peak (decomposition) from 275 -375°C.

Applicant's summary and conclusion

Conclusions:
No boiling point can be assessed due to decomposition of the substance
Executive summary:

In a test using differential scanning calometry, no boiling point could be assessed due to decomposition of the substance at 275 °C and above.
