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.

Properties

Chemical

Hydrazine nitrate will burn if ignited and may even explode.

Physical

Hydrazinium nitrate is a white crystalline solid, very soluble in water.

Explosive

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.[1]

Availability

Hydrazine nitrate is best synthesized.

Preparation

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.

Projects

Handling

Safety

Hydrazine nitrate is explosive. Handle it with care

Storage

Don't store it for long, use it as quickly as possible.

Disposal

Dilution in water, followed by destruction with acidified hypochlorite solution.
