Abstract: An economical and effective explosive composition is manufactured by combining appropriate proportions of activated ammonium nitrate, a fuel and preferably a sensitizer. The preferred fuel is a liquid hydrocarbon derivative or a liquid or solid hydrocarbon derivative which is soluble in the sensitizer and which has a fuel value greater than that of the sensitizer. The preferred sensitizers are nitroalkane, or dinitroaromatic compounds most preferably nitromethane. The explosive composition is made more effective through an activation procedure upon the ammonium nitrate. The ammonium nitrate utilized with the present invention is in the form of prills, porous spherical pellets. These prills can be activated by adding a small amount of water to the prills, thoroughly mixing the water so that it is all absorbed, heating the prills to an elevated temperature, evaporating the water from the prills, and then preferably cooling the prills.

Abstract: A method for treating an aqueous solution of aromatic explosives whereby losive molecules are destroyed and the resulting effluent is safe for disposal. An additive, such as acetone or hydrogen peroxide, is added to an aqueous solution of aromatic explosives and this mixture is exposed to ultraviolet light. The light exposure of the additive provides a free radical which strips hydrogen molecules from the aromatic explosives to change the aromatic explosive to an unstable intermediate compound. Continued exposure of this unstable intermediate compound to ultraviolet light converts the unstable intermediate compound to carbon dioxide and ammonia.
