Barium 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) ... 

Barium chlorite had been added to dimethyl sulphate. The mixture combusted immediately. This behaviour was explained by the formation of methyl chlorite. This accident can also be explained by an oxidation of sulphate by chlorite, whose exothermicity would have caused the compound s self-ignition. The author believes that the instability of methyl chlorite would give rise to a violent detonation rather than an ignition. 

When heated rapidly, barium chlorite decomposes explosively at 190°C, and the lead salt at 112°C. 

For flotation of barite, sodium silicate was used as a depressant and barium chlorite as a barite activator. Barite collector SR82 was composed of petroleum sulphonate, sodium alkyl sulphate and succinamate mixture. The collector was selective towards both fluorite and bastnaesite. Over 96% of the barite was recovered in a relatively high-grade concentrate.

K. G. Thurnlackh and K. F. von Hayn prepared a mixed soln. of potassium chlorate and chlorite by the action of potassium hydroxide free from chlorine on a soln. of chlorine dioxide. Light was carefully excluded, and the soln. was evaporated in vacuo at 45°-50°—potassium chlorate separated out first, and after further evaporation, alcohol was added, and the clear alcoholic soln. evaporated. Needle-like crystals of potassium chlorite, KC102, were obtained which deliquesced on exposure to air. As already indicated in connection with the preparation of the acid, G. Bruni and G. Levi made the potassium chlorite by reducing a soln. of potassium chlorate with oxalic acid and A. Reychler, sodium chlorite, by the action of chlorine dioxide on a soln. of sodium peroxide. Sodium chlorite, NaClQ2, can be also made by double decomposition by treating a soln. of barium chlorite with sodium sulphate and evaporating the clear soln. in vacuo. 

Barium Chlorite, Ba(C102)2 was prepd in soln by action of nascent HC102 on the basic carbonate. The salt could not be separated from soln because of its instability Refs l)Mellor(l939), 512 2)Partington (1950), 272 3)G.R.Levi R.Curti, Ricerca-Sci 23, 1798-801(195 3) CA 48, 135 09(195 4)...

The only definitely known halous acid, chlorous acid, is obtained in aqueous solution by treating a suspension of barium chlorite with sulfuric acid and filtering off the precipitate of barium sulfate. It is a relatively weak acid (KA <= 10 2) and cannot be isolated in the free state. Chlorites (MC102) themselves are obtained by reaction of C102 with solutions of bases ...
