Any other information on results incl. tables

Thermal Stability

The DSC-measurement in a closed glass crucible showed an exothermal decomposition in the temperature range of 345 - 370 °C with an energy of 719 J/g.

Explosive Properties

The decomposition energy was above 500 J/g. Therefore the test on explosive properties was performed.

Mechanical sensitivity (friction)

No explosion was observed within 6 tests using a pin load with 360 N. Only a changing of colour was observed.

Mechanical Sensitivity (Shock) :

No explosion within 6 tests using a mass of 10 kg falling from a height of 0.4 m was observed. Only a decomposition of the test item was observed.

Thermal sensitivity:

Three tests with a circular nozzle plate with a hole of 2 mm diameter were performed. The following table gives the results of the thermal stability.

Test no.	Weight of test item (g)	Nozzle width (mm)	t1 (s)	t2 (s)	Reaction	Appearance; Number of fragments
1	13.5	2.0	21	>300	flame	0
2	13.2	2.0	20	>300	flame	0
3	13.2	2.0	20	>300	flame	0

t1: time to any reaction, e.g. whistle or flame

t2: time to main reaction, e.g. rupture of tube or flashing
