Explosiveness

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.

Key result

Operating temp.:

>= 220 - <= 290 °C

Remarks on result:

other: exothermic effect

Sublimation:

not determined

Transformation products:

not specified

In the temperature range of 220 – 290 °C, an exothermic effect can be observed, with an average decomposition energy of -50 J/g. No further thermic effects could be detected. At approx. 420 °C the pressure in the crucibles started to raise.

Conclusions:

The test item Imidazolium compounds, 2-C4-8-alkyl-1-(2-carboxyethyl)-4,5-dihydro-3-(hydroxyethyl), hydroxides, sodium salts (CAS no. 70983-43-6) showed one exothermic effect in the temperature range of 220 – 290 °C, with a decomposition energy of -50 J/g.

Executive summary:

The test item Imidazolium compounds, 2-C4-8-alkyl-1-(2-carboxyethyl)-4,5-dihydro-3-(hydroxyethyl), hydroxides, sodium salts (CAS no.70983-43-6) showed one exothermic effect in the temperature range of 220 – 290 °C, with a decomposition energy of -50 J/g.
