Remarks on result:

other: 1st exothemic reaction: 80 J/g at onset temperatue 195 °C; 2nd exothemic reaction: 230 J/g at onset temperatue 295 °C; 3rd exothermic reaction: 70 J/g at onset temperatue 395 °C

Results

1.Reaction
Onset-temperature	195 °C
Peak temperature	198 °C
Energy release	80 J/g

 

2.Reaction
Onset-temperature	295 °C
Peak temperature	320 °C
Energy release	230 J/g

 

3.Reaction
Onset-temperature	395 °C
Peak temperature	474 °C
Energy release	70 J/g

The exothermic peak of 80 J / g at 195 ° C will never reach a SADT > 75 ° C.

Since we have a solid phase transformations here are clearly visible and the resulting energy goes into the melt.

The estimated SADT is thus > 75 ° C.

Therefore the substance is not classified as self-reactive.
