  • Explosives containing ammonium nitrate and nitrated amines
    Patent number: 4110136
    Abstract: An explosive composition containing essentially of an intimate mixture of15 to 45% by weight of a particulate high explosive from the group consisg of RDX (1,3,5-trinitro-1,3,5-triazacyclohexane) and HMX (1,3,5,7-tetranitro-1,3,5,7-tetraazacyclooctane and mixtures thereof,15 to 50% by weight of ammonium nitrate, and20 to 60% by weight of ethylenediamine dinitrate;Wherein the weight ratio of ammonium nitrate to ethylenediamine dinitrate is from 1:2.5 to 1.5:1, respectively, and particularly about 1:1. These explosive compositions provide an unexpectedly high explosive output with a relatively low content of RDX and/or HMX, and an equivalent output with much less RDX than conventional explosive compositions consisting of mixtures of RDX with AN and/or TNT.
