Abstract: This invention is an improved process of making azidodeoxycellulose a hig energetic ingredient for use in a propellant. The process is accomplished by nitrating cellulose to nitrocellulose, converting the nitrocellulose in sequence to the iodine derivative, and finally reacting the iodine derivative of cellulose with sodium azide to produce azidodeoxycellulose having up to about 1.5% residual nitrogen as nitrate groups.

Abstract: A method for destroying organic explosives, such as RDX and HMX, by hydroolysis comprises contacting liquors containing waste explosive, produced in the manufacture and processing of the explosives, with hydrogen in the presence of a heterogeneous hydrogenation catalyst, such as nickel-on-kieselguhr, for a sufficient period to destroy the explosives. The method is simple and economic and destroys the explosives, which are considered to be toxic, hazardous and non-biodegradable in soil and hence are not amenable to landfill or discharge into rivers etc., thereby eliminating or reducing the attendant pollution problems to acceptable levels.

Abstract: A process for recovering pure 2,4,6-trinitrotoluene (TNT) from a crude TNT ixture containing unsymmetrical TNT isomers which comprises forming a homogeneous powder of the crude TNT and silica gel, introducing said powder at the top of a silica gel packed column, and resolving the TNT mixture into its component isomers by contacting said powder with a developing solvent system which is not reactive with the component isomers selected from the group consisting of polar organic solvents, non-polar organic solvents, and mixtures thereof having an energy of adsorption adequate to selectively adsorb the individual TNT isomers, such as a mixture of polar acetonitrile and non-polar trichloro trifluoroethane.

Abstract: 2,2', 4,4', 6,6'-hexanitrobibenzyl, an intermediate compound used for mak hexanitrostilbene, is prepared by dissolving trinitrotoluene in a solvent system comprising a water-immiscible solvent and an aliphatic alcohol and then adding a metal hypochlorite solution containing a metal hydroxide to the trinitrotoluene solution to form the hexanitrobibenzyl. The compound is then separated from the reaction mixture.

Abstract: A process of making azidodeoxycellulose nitrate in yields as high as 90 pent. The process initially involves the conversion of cellulose to the mesylate or tosylate derivative. This is followed by reacting the above cellulose derivative with a metallic azide to produce azidodeoxycellulose. Thereafter, the azidodeoxycellulose is nitrated thereby producing azidodeoxycellulose nitrate which is a propellant.
