Upstream Downstream Industry
Nature
colorless transparent orthogonal crystals or white particles. Melting point 169.5 ℃,d 1.72 I tasteless. Moisture absorption, caking is very strong. Soluble in water, alcohol, acetone and ammonia solution, insoluble in ether. 19 The product is dissolved in 0.5 ml water, 0.1 ml boiling water, about 20ml ethanol, about 8ml methanol. Its 0.1 mol/L aqueous solution pH 5. 43. It rapidly decomposes and generates water and nitrous oxide at about 210 ° C., and then explodes when heated. Various organic impurities can significantly increase the explosivity of ammonium nitrate. Mixing with reducing agents, organics, combustible materials such as sulfur, phosphorus or metal powders, etc. can form explosive mixtures.
Preparation Method
nitric acid was mixed with water. Ammonia was added until a significant ammonia odor was present. Heat, filtration. Evaporation, concentration to the liquid surface to form a crystalline film, with ice-cooling, Suction filtration crystallization, drying at 40~50 deg C, to obtain pure ammonium nitrate.
Use
Can be used as analytical reagents, oxidants, refrigerants. It is used as fertilizer in agriculture, and the total nitrogen is about 34%, which is called quick-acting fertilizer. A large number of smoke-free powder for the manufacture. Chemical industry for the manufacture of nitrous oxide, pharmaceutical vitamin B. The light industry produces alkali-free glass.
Safety
rat oral LDso:4820mg/kg. Strong oxidant. When combustible materials are on fire, they can contribute to the fire. When mixed with a combustible powder, an intense reaction can occur and the explosion occurs. It can also be triggered by strong vibration. Explosion can occur when heated sharply. It is strictly prohibited to mix with acids, flammable substances, organic substances, reducing agents, spontaneous combustion substances and wet flammable substances.
