    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: Unsymmetrical TNT isomers are removed from solid or molten crude TNT by treatment with aqueous ammonium sulfite. The yield of purified TNT is significantly greater by treatment with aqueous ammonium sulfite than with conventional sodium sulfite ("sellite") at acceptable levels of isomer removal. By use of ammonium bisulfite together with ammonium sulfite or operation in a closed system to avoid loss of ammonia, high yields of TNT with essentially complete removal of TNT isomers can be obtained at low sulfite levels.
