Overview

Guanidine nitrate is the salt formed from guanidine and nitric acid. It has the chemical formula C(NH2)3NO3. 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\ x\ \tfrac {s}{kg}).[1]

Safety

Hazards:

  • May explosively decompose on shock, friction, or concussion.
  • May explode on heating.
  • On combustion, forms toxic and corrosive fumes including nitric acid and nitrogen oxides.
  • The substance is a strong oxidant and reacts with combustible and reducing materials.

Routes of exposure:

  • The substance can be absorbed into the body by ingestion.
  • A nuisance-causing concentration of airborne particles can be reached quickly when dispersed, especially if powdered.

Effects of short-term exposure:

  • The substance is severely irritating to the eyes and the skin.
  • Harmful if inhaled, swallowed or absorbed through the skin.

Notes
