ABSTRACT:
A process of degrading nitramines by mixing the nitramine with an aqueous dispersion of metal powders and by heating the mixture is disclosed. HMX and RDX are typical nitramines which are degraded according to the present invention. Metal powders which have been successfully used include aluminum and zinc. The weight ratio of nitramine to metal powder is less than about 17:1. The aqueous mixture of nitramine and metal powder is preferably heated to a temperature greater than about 50.degree. C. and up to the boiling point of the mixture. Best results have been obtained when an aqueous base is used in connection with the metal powder. Aqueous ammonia and dilute hydroxide salt solutions are currently preferred aqueous base solutions.
