Patent number: 7101449Abstract: 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, may be 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.Type: GrantFiled: August 22, 2003Date of Patent: September 5, 2006Assignee: Alliant Techsystems Inc.Inventors: Kirstin F. Warner, Louis F. Cannizzo, Robert M. Hajik

Patent number: 6350871Abstract: CL-20 is crystallized from a solution containing a CL-20 organic solvent and a CL-20 non-solvent miscible with the solvent. The CL-20 non-solvent is a nitrate ester, preferably poly(glycidyl nitrate) and/or triethyleneglycol-dinitrate, although other nitrate ester plasticizers having acceptable volatilities and impact sensitivities can be used. The solution is saturated with CL-20, and CL-20 is then crystallized from the saturated solution by adding &egr;-polymorph CL-20 crystalline seeds to the solution and evaporating off the CL-20 solvent, preferably under vacuum. The nitrate ester non-solvent is then separated from the crystalline CL-20, such as by filtration of the CL-20 crystals or by diluting the slurry of non-solvent and CL-20 with an environmentally acceptable solvent that is miscible with the non-solvent but in which the CL-20 is insoluble.Type: GrantFiled: March 21, 2001Date of Patent: February 26, 2002Assignee: Alliant Techsystems Inc.Inventors: Andrew J. Sanderson, Richard S. Hamilton, Kirstin F. Warner
