Lead chlorite

Many of the metal chlorites are not particularly stable and will explode or detonate when stmck or heated. These include the salts of Hg", Tl", Pb ", Cu", and Ag". Extremely fast decomposition with high heat evolution has been noted for barium chlorite [14674-74-9] Ba(Cl02)2, at 190°C, silver chlorite [7783-91-7] AgC102, at 120°C, and lead chlorite [13453-57-17, at 103°C (109). Sodium chlorite can be oxidized by ozone to form chlorine dioxide under acidic conditions (110) ... 

A mixture of 150 parts of oxalic acid, 40 of potassium chlorate, and 20 of water is heated to 60°, and the soln. cone, in vacuo at 50° until it begins to crystallize. The cold liquid i3 then treated with 3 volumes of absolute alcohol, when potassium carbonate is precipitated. Fine deliquescent needles of potassium chlorite can be obtained by fractional crystallization in vacuo. The residue gives a further crop of crystals of the chlorite by treatment with 95 per cent, alcohol. Small yellow crystals of silver or lead chlorites can be obtained by double decomposition. 

N. A. E. Millon found that a soln. of alkali chlorite gives a yellow precipitate of lead chlorite, Pb(C102)2, or of silver chlorite, AgC102, when treated respectively with lead or silver nitrate. On recrystallization from hot water, lead and silver chlorites are obtained in yellow plates. J. Schiel also made lead chlorite by treating a soln. of barium or calcium chlorite with lead nitrate an excess of the lead nitrate is to be avoided because of its solvent action. Fine sulphur yellow crystals can be obtained from a warm soln.—50°-60°—of the salt in calcium chlorite. The dry salt explodes at 126° according to N. A. E. Millon, at 100° according to J. Schiel. It explodes when triturated with flowers of sulphur or antimony sulphide. It behaves like silver chlorite with hydrogen sulphide and with sulphuric acid. 

Lead Chlorite, Pb(C102)2, monocl yel crysts, mp explodes at 100° can be pptd when a soln of Na chlorite is acidified with acetic acid and treated with Pb nitrate. Lead chlorite mixed with sugar detonates violently on percussion, and such a mixt has been used in detonators (Ref 5)... 

Barium and lead chlorites explode on rapid heating at about 460 K and 385 K, respectively. The decompositions of NaQOj (above 413 K) and of AgCCO (above 358 K) are first-order reactions and the values of are 227 and 109 kJ mol, respectively. The major products of AgCCOj decomposition above 373 K are Ag, AgjO and QO. The thermal stabilities of these four chlorites decrease [27,28] in the same sequence (Na, Ba, Ag, Pb) as the ionic character of these solids, covalent character is associated with greater reactivity.
