It is a colorless, water-soluble salt. It is produced on a large scale as high energy fuel used as gas generator and solid rocket propellant applications. Its more official name is guanidinium nitrate, but the incorrect term guanidine nitrate is widely used. Production and propertiesAlthough it is the salt formed by neutralizing guanidine with nitric acid, guanidine nitrate is produced industrially by the reaction of dicyandiamide (or calcium salt) and ammonium nitrate.[1] It has been used as a monopropellant in the Jetex engine for model airplanes. It is attractive because it has a high gas output and low flame temperature. It has a relatively high monopropellant specific impulse of 177 seconds (1.7 kN·s/kg).[2] Guanidine nitrate's explosive decomposition is given by the following equation: H6N4CO3 (s) → 3 H2O (g) + 2 N2 (g) + C (s) SafetyThe compound is a hazardous substance, being an explosive and containing an oxidant (nitrate). It is also harmful to the eyes, skin, and respiratory tract.[1] Notes1. ^1 Thomas Güthner, Bernd Mertschenk and Bernd Schulz "Guanidine and Derivatives" in Ullmann's Encyclopedia of Industrial Chemistry, 2006, Wiley-VCH, Weinheim. {{DOI|10.1002/14356007.a12_545.pub2}} {{Reflist}}2. ^1000 lbf/in2 (700 kPa) chamber pressure, 14.7 lbf/in2 (101 kPa) exit pressure, shifting equilibrium theoretical performance.
