Administrative data

Endpoint:
explosive properties of explosives
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because there are no chemical groups present in the molecule which are associated with explosive properties
Justification for type of information:
The decomposition energy of the substance is less than 500J/g as determined by DSC-Measurement. See further information in the cross-ref.

In the temperature range of 110 °C – 135 °C, an endothermic effect was observed, which was directly followed by an exothermic effect in the temperature range of 135 – 190 °C, with a decomposition energy of -190 J/g. A second exothermic effect was detected in the temperature range of 200 – 290 °C, with a decomposition energy of -80 J/g. The test was terminated at 300 °C.

Conclusions:
In the DSC-measurements the test item ATP, Di-Na (CAS 987-65-5) showed an endothermic effect in the temperature range of 110 °C – 135 °C, which was directly followed by an exothermic effect in the temperature range of 135 – 190 °C, with a decomposition energy of -190 J/g. A second exothermic effect was detected in the temperature range of 200 – 290 °C, with a decomposition energy of -80 J/g.
Executive summary:

In the DSC-measurements the test item ATP, Di-Na (CAS 987-65-5) showed an endothermic effect in the temperature range of 110 °C – 135 °C, which was directly followed by an exothermic effect in the temperature range of 135 – 190 °C, with a decomposition energy of -190 J/g. A second exothermic effect was detected in the temperature range of 200 – 290 °C, with a decomposition energy of -80 J/g. The test was terminated at 300 °C.
