Aminoguanidinium nitrate (incorrectly but often written aminoguanidine nitrate) is an organic chemical compound used as energetic material, especially in hobby experiments.

Properties

Chemical

Aminoguanidinium nitrate decomposes if heated, sometimes with flame. It has been mentioned in the literature that on evaporation of an aqueous solution with a steam bath the salt violently exploded.[4] A solution of 25 g of the nitrate was boiled down in vacuum, the solid white residue exploded for no apparent reason, windows where penetrated by flying glass shrapnel and a coworker suffered lacerations to face and arms. The authors note that the salt was made a few more times without explosion, and the cause of the accident could not be determined.[5]

Physical

Aminoguanidinium nitrate is a white solid.

Explosive

Aminoguanidinium nitrate can explode under heat and mechanical stress.

Availability

It is sold by chem suppliers.

Preparation

Aminoguanidinium nitrate can be easily prepared by reacting aminoguanidinium bicarbonate with nitric acid.[6]

Can also be made by reducing nitroguanidine with Zn powder in acid, followed by reaction with nitric acid..

Projects

  • Energetic materials

Handling

Safety

Should be handled with care.

Storage

In closed bottles.

Disposal

Controlled incineration should suffice.
