Abstract

1321731 Explosive compositions IMPERIAL CHEMICAL INDUSTRIES Ltd (B N ROY) 28 March 1972 [3 May 1971] 12735/71 Heading C1D A slurry explosive composition comprises an inorganic oxygen-supplying salt, a solvent for the salt, a polysaccharide thickener, a fuel, and, for aeration of the composition, a nitrogen compound having a specified formula and an oxidizing agent reactable with the nitrogen compound to produce gas. Suitable nitrogen compounds are hydroxylamine and hydrazine and their hydrochlorides, sulphates and nitrates, phenylhydrazine and its hydrochloride and nitrate, 2, 4-dinitrophenylhydrazine, phenylsulphonyl hydrazide, semicarbazide and its hydrochloride and nitrate, phenyl thiosemicarbazide, and benzoyl hydrazide. Preferred oxidising agents are potassium iodate, potassium periodate, copper sulphate, potassium ferricyanide, lead dioxide, ceric ammonium nitrate, potassium permanganate, potassium dichromate, mercuric oxide, hydrogen peroxide, and peroxysulphuric acid. The oxygen-supplying salt may be ammonium, sodium, potassium, barium or calcium nitrate or mixtures thereof. Suitable solvents are water, formamide, dimethylsulphoxide, and ethylene glycol. Fuels referred to are Al, Al Alloy, Si, ferrosilicon, ferrophosphorus, sulphur, carbon, sugar, urea, thiourea, TNT, PETN, RDX, smokeless powder, nitrocellulose, and nitrostarch. Suitable thickeners are carboxymethyl cellulose, guar gum, carob seed gum, karaya gum, locust bean gum, hydroxyethyl cellulose, tamarind flour, and starch. Cross-linking agents may be added, for example potassium pyroantimonate, zinc chromate, or sodium or potassium dichromate in conjuction with potassium antimony tartrate. Other ingredients used in examples are isopropyl nitrate and ethyl centralite.
