Encyclopedia > Lead styphnate

Lead styphnate (lead 2,4,6-trinitroresorcinate, (C6HN3O8)Pb), whose name is derived from styphnic acid, is a toxic explosive used as a component in primer and detonator mixtures for less sensitive explosives, such as nitroglycerine. Resorcin (or resorcinol) is the (1,3) isomer of dihydroxybenzene (dihydric phenol). ... Styphnic acid (2,4,6-trinitro-1,3-benzenediol, or (NO2)3. ... The percussion cap or primer was the crucial invention needed to make fire-arms that could fire in any weather. ... A detonator is a device used to trigger bombs, shaped charges and other forms of explosive material and explosive devices. ... This article is concerned solely with chemical explosives. ... Nitroglycerin (also nitroglycerine, trinitroglycerin, or glyceryl trinitrate) is a chemical compound, a heavy, colorless, poisonous, oily, explosive liquid obtained by nitrating glycerol. ...


There are two forms of lead styphnate: six-sided monohydrate crystals and small rectangular crystals. Lead styphnate varies in color from yellow to brown. Lead styphnate is particularly sensitive to fire and the discharge of static electricity. When dry, it can be readily detonated by static discharges from the human body. The longer and narrower the crystals, the more susceptible lead styphnate is to static electricity. Lead styphnate does not react with metals and is less sensitive to shock and friction than mercury fulminate or lead azide. Lead styphnate is only slightly soluble in water and methyl alcohol and may be neutralized by a sodium carbonate solution. It is stable in storage, even at elevated temperatures. Hydrates are compounds formed by the union of water with some other substance, generally forming a neutral body, as certain crystallized salts. ... Static electricity is a class of phenomena involving the imbalanced charge present on an object, typically referring to charge with voltages of sufficient magnitude to produce visible attraction, repulsion, and sparks. ... Mercury fulminate (Hg(ONC)2) is a primary explosive. ... Lead azide (Pb(N3)2) is an explosive and toxic crystalline compound. ... Water (from the Old English word wæter; c. ... Methanol, also known as methyl alcohol or wood alcohol, is a chemical compound with chemical formula CH3OH. It is the simplest alcohol, and is a light, volatile, colourless, flammable, poisonous liquid that is used as an antifreeze, solvent, fuel, and as a denaturant for ethyl alcohol. ... Sodium carbonate or soda ash, Na2CO3, is a sodium salt of carbonic acid. ...

Lead is used in bullets, batteries, fishing sinkers, old toy soldiers, and for decades it was an additive in gasoline.
Because lead is absorbed by the bones and stored there quite tenaciously, archaeologists have been able to examine the bones of ancient people in pre-industrialized societies and estimate their lead levels.
