new primary explosive?


On megalomania site there is a recipe for a stuff called lead trinitrooxybenzoate. In this recipe, solution of lead nitrate is mixed with solution of sodium benzoate. Then, to this mix is added some ethyl alcohol and suddenly a yellow percipate appears. Mega site says that it is not sensitive to shock or friction but very sensitive to flame. Could this compound be made so easily???

Lead TriNitoOxyBenzoate?
Sounds very similar to Lead Picrate...

It seems that something may have been forgotten in that procedure. I dont think that it is possible to add three nitro groups on a benzene ring with lead nitrate as the nitrating agent.

Heres the link

I have no idea about trinitro-oxybenzoates but am rather curious as to the possible use of trinitrobenzoates. I came across a synth for trinitrobenzoic acid which requires the oxidation of TNT with sodium dichromate. From there I figure one could just react the trinitrobenzoic acid solution with PbO to form lead trinitrobenzoate.

Maybe with lead dioxide. The acid has 3 nitro groups, a benzoic acid group and an OH group. Trinitrobenzoic acid would need to be oxidised.

you're right Marvin
oxybenzoic acid is a misleading name for hydroxybenzoic acid I'm 99% sure it's the meta isomer in this case. thus trinitrooxybenzoic acid is 3-hydroxy 2,4,6-trinitrobenzoic acid which is a dibasic acid and is probably made from oxydation of trinitro m-cresol
Edit: I think Marvin you took a123x wrong. he wasn't refering to lead trinitro<b>oxy</b>benzoate but was refering to lead salt of trinitrobenzoic acid to be used as a primary explosive. there should be a reason it has so rarely been mentioned in the art (if at all) MAYBE it has high solublity in water which makes it hard to obtain good yields and fine crystals.. again I said maybe...

My apologies a123x, I read it wrong.

Thankyou Kabooom and I agree, Id think the higher number of organic molecules per lead ion probably gives it poorer physical properties.

Also, it'd readily decarboxylate, as when making TNB - stability is probably an issue.
