Abstract
Abstract An explosive ternary nitrate mixture of ethylenediamine dinitrate, ammoniumitrate, and potassium is prepared by mixing together approximately stoichiometric amounts of aqueous nitric acid, ethylenediamine, ammonia, and potassium hydroxide at a temperature of less than about 130° C. The additions can be made simultaneously or sequentially in any order.
