Molecular structure

The molecular structure of the test substance does not contain any chemically instable or highly energetic groups that might lead to an explosion. The impurities, present for <5% in the test substance, were not taken into account but it is not to be expected that these have any influence.

Oxygen balance

The oxygen balance of a compound is the difference between the oxygen content of the compound and that required to fully oxidize the carbon, hydrogen and other oxidisable elements to carbon dioxide, water, etc. Nitrogen is not considered oxidisable and is usually liberated as the gaseous element during explosive decomposition.

The oxygen balance is calculated for the chemical reaction:

CcHhOo + [c + (h/4) – (o/2)] O₂→c CO₂+ (h/2) H₂O

where c, h and o are the amounts of carbon, hydrogen and oxygen atoms respectively.

Oxygen balance (%) = -1600 x [2 x c + (h/2) – o] / molecular weight

If there is a deficiency of oxygen, the balance is negative, while an excess of oxygen gives a positive balance. Compounds with a positive balance can act as oxidants and are often explosive in nature. However, there are known explosives with an oxygen balance of –64%. Compounds with an oxygen balance which is more negative than –200% are not considered to pose an explosive risk.

Using C₇₀H₁₂₈O₁₀as molecular formula and 1129.8 g/mol as molecular weight, theoxygen balance for the test substance was calculated to be –275 %. This value is outside the region where there may be a potential for explodability.
