Lead styphnate
What Lead styphnate is, and how MuniRem® treats it, in plain language.
What it is
Lead styphnate is a primary explosive, the lead salt of trinitroresorcinol (TNR). It is used in primers and detonators. It is very sensitive to static and friction, and it also carries toxic lead.
How MuniRem® treats it
At an Army laboratory, a 4,300 ppm TNR solution turned crimson-purple on contact with MuniRem. TNR fell to non-detect at every dose tested. In a separate project, MuniRem solution was sprayed in a former TNR production building, next to a lead styphnate building, so it could be safely demolished.
- MuniRem solution is sprayed on building surfaces or mixed with the material.
- The styphnate (TNR) part is reduced on contact and changes color as the nitro groups are removed.
- The lead is released and reacts with sulfur from the reagent to form insoluble lead sulfide.
- An EPA-certified laboratory tests the treated material before any disposal decision.
What it becomes
TNR to non-detect, Lead as insoluble lead sulfide, Sulfate.
Where it's found
Primer and detonator plants and former initiator production buildings.
