Priming compositions lead-free

Primer mixtures can be divided today into six categories (a) mercuric and corrosive, (b) mercuric and noncorrosive, (c) nonmercuric and corrosive, (d) nonmercuric and noncorrosive, that is, Sinoxyd type, (e) Sintox type, that is, lead free, and (f) miscellaneous (unusual priming compositions).

Sinoxid = non eroding primer composition (german) 288 SINTOX = lead free priming composition (german) 289 Sixolite = tetramethylolcyclohexanol pentanitrate 310... 

The compound is sparingly soluble in water, soluble in methanol and ethanol, and readily soluble in acetone, nitroglycerine, nitrobenzene, aniline, pyridine, and acetic acid. It rapidly darkerns in sunlight. It is of interest for -> Lead-free Priming Compositions. 

The product can be obtained by treating 2,4,6-trichloro- 1,3,5-trinitrobenzene with an alkali metal azide in alcoholic solution. It is a lead-free - initiating and powerful explosive and does not produce toxic fumes (- Lead-free Priming Compositions). The product undergoes a slow conversion into hexanitrosobenzene,... 

Uses Lead-TNP is used in initiating compositions in place of lead styphnate or diazodinitrophenol for blasting caps and detonators, in priming compositions in place of mercury fulminate or in combination with sulfur nitride, triazoles, or tetrazoles, for use in bullet primers and the like. Lead-TNP can also be used in fireworks to detonate black powder for increased bursting effects in aerial shells. Lead-TNP should be handled with care. Never store dry, and keep submerged in a water free solvent...
