Explanation

White crystal, non hygroscopic, non volatile, little water solubility in general organic solvents, slightly soluble in water, sulfuric acid, nitric acid, methanol and acetone, soluble in dimethyl sulfoxide and dimethylformamide. It has weak alkalinity and can form salts with strong acids. It has strong reaction ability and is an important intermediate for organic synthesis and explosive synthesis. Guanidine nitrate is generated by the reaction of ammonium nitrate and urea, and then treated with concentrated sulfuric acid to obtain guanidine nitrate. During World War I, it was used to charge projectiles; In World War II, it was used as a component of composite explosive. Due to the low explosion temperature of nitroguanidine, the three base gunpowder composed of it, nitroglycerin and nitrocotton is called cold propellant, which has little erosion to shells and can extend the service life of gun barrel. nitroguanidine has low sensitivity, and its based mixed explosives have low vulnerability and can be used for a variety of projectile charges.
