A process for the production of the ammonium salt of 3,5-dinitro-1,2,4-triazole (ADNT) has been developed. The process includes solvent extraction of 3,5-dinitro-1,2,4-triazole (DNT) with water-insoluble, high-molecular-weight amines and the preparation of the ammonium salt with anhydrous ammonia. The extraction of DNT is based on the reaction of the free-base form of the amine with the organic acid to form the water-insoluble DNT-amine salt. The production of ADNT is achieved by regeneration of the amine to its free-base form with a basic stripping agent in a suitable diluent. The complete process requires 6 to 7 h on a laboratory bench scale and appears to be feasible for large-scale production. The process could be applied to the production of any ammonium salt with properties similar to those of ADNT.
