[Safety Profile]

A powerful oxidizer and an allergen. See also NITRATES. A relatively stable explosive that has, however, caused many industrial explosions. Violent or explosive spontaneous reactions with acetic anhydride + nitric acid, ammonium sulfate + potassium, copper iron(Ⅱ) sulfide, sawdust, urea, barium nitrate, hot water, and ammonium chloride + water + zinc. Forms heator shock-sensitive explosive mixtures with acetic acid, aluminum + calcium nitrate + formamide (a blasting explosive), ammonia, charcoal + metal oxides (e.g., rust, copper oxide, zinc oxide above 80℃), chloride salts (e.g., ammonium chloride, calcium chloride, iron(ⅡI) chloride, and aluminum chloride), cyanoguanidine, feruH2ers (e.g., super phosphate + organic materials above 90℃), hydrocarbon oils, powdered metals (e.g., aluminum, antimony, bismuth, cadmium, chromium, cobalt, copper, iron, lead, magnesium, manganese, nickel, tin, zinc, brass, stainless steel, titanium, and potassium), nonmetals (e.g., charcoal, and phosphorus), organic fuels (e.g., wax, oils, and stearates), potassium permanganate, sugar, sulfur, and trinitroanisole. Reaction with alkali metals (e.g., sodium) forms an explosive product. Ignites on contact with ammonium dichromate, potassium dichromate, potassium chromate, barium chloride, sodium chloride, potassium nitrate, and chromium(V1) salts. Can ignite when mixed with acetic acid. Use water in large amounts to fight fire. It is important that the mass of materials be kept cool and that burning be extinguished promptly. Ventilate well. May explode under confinement and high temperatures. When heated to decomposition it emits highly toxic fumes of NOx. Can react vigorously with reducing materials.

[General Description]

A colorless crystalline solid. Soluble in water. Does not readily burn but will do so if contaminated with combustible material. Accelerates the burning of combustible material. Produces toxic oxides of nitrogen during combustion. Used to make fertilizers and explosives, and as a nutrient in producing antibiotics and yeast.
[Reactivity Profile]

The hazards of AMMONIUM NITRATE have been well studied because of several extremely severe explosions [Chem. Eng., 1962, 70, 91; Bretherick, 5th Ed., 1995]. Mixtures with alkyl esters may explode, owing to the formation of alkyl nitrates. Mixtures with phosphorus, tin(II) chloride or other reducing agents may react explosively [Bretherick 1979 p. 108-109]. A mixture with aluminum powder (also zinc, cadmium, copper, magnesium, lead, cobalt, nickel, bismuth, chromium, and antimony) can be used as an explosive. A number of explosions in which ammonium nitrate and aluminum were mixed with carbon or hydrocarbons, with or without oxidizing agents have occurred [Mellor 5:219 1946-47]. A mixture with acetic acid ignites when warmed, especially if concentrated [Von Schwartz p. 322 1918]. Causes the decomposition of sodium hypochlorite within a few seconds [Mellor 2 Supp. 1:550 1956].
[Air & Water Reactions]

Water soluble. Hot aqueous solutions of the nitrate above 50% conc., under confinement may decompose explosively. This process is aided catalytically with such substances as nitric acid and chloride ion, [Chem. Abs., 1982, 97, 78074].
[Health Hazard]

Inhalation, ingestion or contact (skin, eyes) with vapors or substance may cause severe injury, burns or death. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may cause pollution.
[Potential Exposure]

Used in the manufacture of liquid and solid fertilizer compositions, industrial explosives and blasting agents from ammonium nitrate, matches; antibiotics; in the production of nitrous oxide.
[Fire Hazard]

These substances will accelerate burning when involved in a fire. Some may decompose explosively when heated or involved in a fire. May explode from heat or contamination. Some will react explosively with hydrocarbons (fuels). May ignite combustibles (wood, paper, oil, clothing, etc.). Containers may explode when heated. Runoff may create fire or explosion hazard.
[First aid]

If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit.

Questions And AnswerBack Directory
[Brief Introduction]

Ammonium nitrate, is a colorless rhombic or monoclinic crystal at room temperature. It can be decomposed into water and nitrous oxide at 210 ° C. Upon severe heating at 300 ℃ above, it is subject to decomposition into nitrogen, oxygen and water. It is soluble in water, methanol and ethanol. It dissolution in water can absorb a lot of heat and reduce the temperature. It is one of the major nitrogen fertilizer varieties in the world today, accounting for about 3.5% of the total amount of nitrogen fertilizer in our country. The nitrogen form is nitrate, which belongs to the nitrate nitrogen fertilizer. In fact, ammonium nitrate both nitrate and ammonium nitrogen, but its nature is more similar to the nitrate nitrogen fertilizer.
Ammonium nitrate has no residue in the soil; and can be all absorbed by crops; being a physiological neutral fertilizer. Ammonium nitrate is suitable for a wide range of soils and crops but is most suitable for dry and dry crops especially suitable for cash crops such as tobacco, cotton and vegetables.
Ammonium nitrate should not be used as a basal fertilizer, because ammonium nitrate, after being applied to the soil, has its dissociated nitrate ions be easily leached into the soil. At the same time, ammonium nitrate should not be used seed manure because of its higher nutrient content, high hygroscopicity, which will affect the germination upon contact with seeds.
Ammonium nitrate, when applied in paddy field, can have its nitrogen content easily leached. Therefore, its efficiency is not comparable to other nitrogenous fertilizers of equal nitrogen content, being only equivalent to 50% -70% of that of ammonium sulfate with equal nitrogen content. The most ideal application is for topdressing, and is most suitable for top-dressing in dry land. The usage amount can be determined according to soil fertility and yield indicators. Should pay attention to the following points:
  • Do not mix with acid fertilizers (such as superphosphate) and alkaline fertilizers (such as ash, etc.) to prevent the reduction of fertilizer efficiency.
  • In the event of caking, gently crush it with sticks; avoid fiercely crushing it to prevent explosion.
  • Apply sealed packaging, pay attention to moisture, heat; store way from combustibles and oxidants.
[Extremely Insensitive Explosives]

Ammonium nitrate is an extremely insensitive explosive that is more detrimental than the safe explosives c4. An industrial 8 # detonator (detonated c4 just 6 # on it) are not enough to detonate a mixture of sensitizer ammonium nitrate. Ammonium nitrate is the most detonating nitric acid explosives with impact sensitivity being: 50kg hammer with 50cm drop height will not cause explosion. The impact sensitivity of the famous explosive nitroglycerin: 200 g hammer at 20cm high drop height will lead to 100% explosion. And once the ammonium nitrate is dissolved in water, the detonation sensitivity is greatly reduced, for which it is impossible to detonate the ammonium nitrate with human power.
