  • Patent number: 6416601
    Abstract: Nitramines are one of the more expensive and often the more plentiful ingredients found in energetic materials, such as solid rocket motor propellants, explosives, and pyrotechnics. By treating aluminized energetic material with an aqueous nitric acid solution containing not more than 55% by weight aqueous nitric acid at a weight ratio of aqueous nitric acid to energetic material of about 4:1 to about 6:1, most constituents of conventional aluminized energetic materials are digested into solution, with the exception of nitramines, which remain substantially insoluble in the aqueous nitric acid and can be recovered without requiring recrystallization of the nitramines. A mineral acid other than nitric acid, preferably hydrochloric acid, is added to increase the rate of aluminum digestion. Treatment of the energetic material can be performed without volatile organic solvents, thus obviating ecological, cost, and safety concerns raised by the use of volatile organic solvents.

  • Patent number: 6013794
    Abstract: The present invention relates to a method of working up and recovering returned explosives which are principally of the military type and which contain both fusible and non-fusible crystalline substances. In accordance with the invention, the returned explosive is treated in a multi-stage process which includes a first leaching stage for removing the non-crystalline, preferably fusible, component of the explosive in the form of trotyl, wax or plastic. The substance used in the leaching stage, principally toluene, does not affect the crystalline components of the explosive. The collected leaching liquid is separated off and the toluene, together with its dissolved content of trotyl or wax, is conveyed onwards for working up.
