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.

Starting at a temperature of 50 °C a first exothermic effect with an energy release of -20 J/g can be observed. This effect is directly followed by an endothermic effect, starting at 80 °C. A second endothermic effect is detected starting at a temperature of 210 °C. This effect leads into a second exothermic effect starting at 230 °C with an energy release of -20 J/g. Subsequently a third exothermic effect starting at 370 °C with an energy release of -20 J/g is observed.

Conclusions:
The test item Disodium beta-glycerophosphat (CAS no. 819-83-0) showed three exothermic effects at temperatures of 50, 230 and 370 °C with an overall decomposition energy of -60 J/g.
Executive summary:

The test item Disodium beta-glycerophosphat (CAS no. 819-83-0) showed three exothermic effects at temperatures of 50, 230 and 370 °C with an overall decomposition energy of -60 J/g.
