CHEMICAL AND PHYSICAL PROPERTIES
| Physical Description | Nitroguanidine is shipped as a slurry or wet mass of pale yellow crystals. If it should dry out it can explode due to shock, heat, flame, or friction. The primary hazard is blast where the entire load can explode instantaneously and not from flying projectiles and fragments. Under prolonged exposure to fire or heat they can explode. |
|---|---|
| Color/Form | Needles, prisms from water /alpha 1-Nitroguanidine/ |
| Melting Point | 239 °C (decomposes) |
| Solubility | Slightly soluble in ethanol; insoluble in ethyl ether; very soluble in alkali |
| Vapor Pressure | 1.43X10-11 mm Hg at 25 °C |
| LogP | log Kow = -0.89 |
| Henry's Law Constant | Henry's Law constant = 4.45X10-16 atm cu m/mol at 25 °C |
| Stability/Shelf Life | Alpha is the usual stable form... |
| Decomposition | Decomposes immediately on melting to form ammonia, water vapor, and solid products. The gases from the decomposition of nitroguanidine are far less erplosive than gases from other similar explosives. |
| Other Experimental Properties | Decomposition at 225-250 °C (depending on speed of heating) giving off ammonia fumes /alpha/ |
| Chemical Classes | Nitrogen Compounds -> Other Nitrogen Compounds |
