    • n guncotton A general name for the nitrates of cellulose, prepared by digesting cotton or other form of cellulose in nitric acid, or preferably in a mixture of nitric and sulphuric acids. A series of nitrates may thus be made, differing in composition and properties according to the strength of acids and time of digestion. Weak acids and short digestion yield trinitro- and tetranitro-cellulose, which dissolve in a mixture of alcohol and ether. This solution is the collodion of commerce. A highly explosive nitrate, to which the name guncotton more properly belongs, is made by digesting clean cotton in a mixture of 1 part nitric acid, specific gravity 1.5, and 3 parts sulphuric acid, specific gravity 1.85, for 24 hours and thoroughly washing the product. This is a hexanitrate of cellulose, C12H14 (NO3)6O10. It can hardly be distinguished by appearance from raw cotton, and is insoluble in alcohol and ether. When ignited it burns quietly, leaving no residue, but by percussion explodes violently, especially if compressed. Its explosive force is much greater than that of gunpowder. It has been used chiefly for torpedoes and submarine blasting, but is now largely superseded by dynamite.
