EDNA, an acronym for ethylenedinitramine, is an insensitive high explosive material similar to TNT or picric acid. Other common names for this explosive include N,N’-dinitro-ethylenediamine; 1,2-dinitrodiaminoethane; and Haleite. EDNA is very stable to shock or friction, but is quite sensitive to heat. It is a very brisant explosive, on the order of common primary explosives, but lacks their inherent sensitivity to shock. EDNA is, however, quite sensitive to heat. Having high stability to shock, but low stability to heat makes EDNA quite unique compared to other explosives. This explosive can be used as either a primary explosive in detonators, as a booster charge, or as a secondary explosive. EDNA containing explosives are sometimes referred to as Haleites, so called because of the scientist involved in their military development Dr. G.C. Hale. Since EDNA does not contain enough oxygen to complete combustion its performance can be markedly increased by mixing with oxidizing compounds.

EDNA is easily prepared from DNEU by refluxing in a round-bottomed flask with an excess of water for an hour or two. Upon cooling EDNA precipitates as beautiful crystals. The product can be poured over a filter to collect them and allowed to dry.
