Detonation rate hydrazine nitrate

Explosive of Audrieth. Mixture of AN 78.5— 83-5, hydrazine nitrate (N2H4.HNO3) 5—10, TNT 7.5, Al powder 0.5, pulverized carbon 3 chalk 0.5% It is claimed that hydrazine nitrate increased considerably the sensitivity and the rate of detonation of the mixt Refs 1) L.F. Audrieth, USP 2704706(1955)... 

Medard [47] established that hydrazine nitrate is an explosive that is readily detonated by an initiating cap, even when the density achieved by loading the product in the molten state is high (1.62 g/cm3). The rate of detonation of a cartridge, 30 mm dia., placed in a cardboard paper case is ... 

Urbanski (Ref 53) also studied the effect of addition of such non-solvent liqs as H20, C7H14, CHO3, iso-CsHuOH, glycerol, castor oil, o-and p-nitrotoluene, PhNH2, and glycerol triacetate, on the deton rate of RDX. He also found that as liq content increased, the D vs %liq curve passes thru a max. Kegler (Ref 65) investigated the effect of the addition of w and aq solns of amm nitrate or hydroxide, hydrazine or nitric acid on the D of RDX. Unfortunately his data are unavailable to us... 

This explosive is more powerful than C-4 plastique explosive. With its high detonation rate and great bristance, it should find some use. It is more sensitive than most explosives obtained from AN, since it is not AN but hydrazine nitrate. This explosive liquid is very corrosive and this should be taken into affect when suitable containers are rounded up in which to place the explosive. Hydrazine is a hard chemical to find. Used as a rocket fuel, obtaining this chemical could arouse suspicion. It is used as a boiler deoxygenator and perhaps could be procured for this purpose. The manufacture is simple with the AN prills being dissolved in the hydrazine by small additions with good ventilation, as ammonia gas is produced by the reaction. 

TNT 7.5, Al dust 0.5, coal 3 and chalk 0.5%. The introduction of up to 10% of hydrazine nitrate in an AN expl markedly increases sensitivity and deton rate. AN and hydrazine nitrate are prefetbably mixed together prior to the addition of other ingredients, or they may be fused, solidified and subdivided prior to such addition (Ref 80) k)An expl obtai ned by neutralization of an acidic nitrated polyol such as NG by the addition of amines or amides such as urea, especially i n the form of a melt with AN i n a eutectic mixt. The expl is stable i n storage, especially when the amine or amide is present in excess(Ref 87)... 

Hydrazine nitrate has a good thermal stability. Its weight loss rate at 100 °C is slower than that of ammonium nitrate [20]. Its explosion point is 307 °C (50 % detonation) and explosion heat is about 3.829 MJ/kg. Because of no carbon elements, the detonation products are not solid and their average molecular weight is small.
