Hydrazine nitrate, or more correctly but rarer used hydrazinium nitrate, is an inorganic compound with the chemical formula N2H4·HNO3 or N2H5NO3. It exists in two crystalline forms, stable α-type and unstable β-type. The former is usually used in explosives.
Hydrazine nitrate will burn if ignited and may even explode.
Hydrazinium nitrate is a white crystalline solid, very soluble in water.
Hydrazine nitrate has good thermal stability. Its weight loss rate at 100 °C is slower than that of ammonium nitrate. Its explosion point is 307 °C (50% detonation) and explosion heat is about 3.829 MJ/kg. Because it has no carbon elements, the detonation products are not solid and their average molecular weight is small. Its explosive velocity has been determined to be 8,690 m/s while its sensitivity is being given the value of 7.4 Nm.
Hydrazine nitrate is best synthesized.
Hydrazine nitrate can be prepared by mixing aqueous solution of hydrazine sulfate with and aq. solution of calcium, barium or lead(II) nitrate. The resulting precipitate is filtered off, and the resulting filtrate is dried to precipitate out the hydrazine nitrate. Drying hydrazine nitrate is difficult, but doable.
Adding ammonium nitrate to an aq. solution of hydrazine (hydrazine hydrate) will cause hydrazine nitrate to precipitate, while ammonia will bubble out of the solution.
Hydrazine nitrate is explosive. Handle it with care
Don't store it for long, use it as quickly as possible.
Dilution in water, followed by destruction with acidified hypochlorite solution.
