Tetryl oxygen balance

Because of their favorable elemental compositions, heteroaromatic nitro compounds represent explosives of high performance (oxygen balance, density, heat of formation and VOD) compared with analogous aromatic explosives [136-138]. With this objective, Licht and co-workers have synthesized some methylnitramine substituted pyridines and triazines, established their structures and characterized them for thermal and impact sensitivities [139]. The data on impact sensitivity, however, indicate that tetryl may not be replaced by these explosives. 

TNBzlN is an expl about as powerful as tetryl (ca 126-7% TNTby Ballistic Mortar Test) and si less sensitive to impact than PETN. It possesses adequate stability and favorable oxygen balance to CO C7H4N40g - 7C0+2H20 + 2NZ... 

It is a more powerful explosive than hexyl or picryl sulphide, mainly due to a more favourable oxygen balance, and also surpasses picric acid. Its sensitivity to impact is of the order of tetryl. 

Tetranitromethane is positive oxygen balance explosive, but it is not sensitive to detonation. Even with 10 g of tetryl explosive can not make it fully detonated.
