Ammonium nitrite Uses

Ammonium nitrite (CAS NO.13446-48-5) is used as a rodenticide, microbiocide and agricultural pesticide, and is acutely toxic to both humans and aquatic organisms.

Ammonium nitrite Production

Ammonium nitrite (CAS NO.13446-48-5) forms naturally in the air and can be prepared by the absorption of equal parts nitrogen dioxide and nitric oxide upon aqueous ammonia.It can also be prepared by oxidizing ammonia with ozone or hydrogen peroxide, or in a precipitation reaction of barium or lead nitrite with ammonium sulfate, or silver nitrite with ammonium chloride. The precipitate is filtered off and the solution concentrated. It forms colorless crystals which are soluble in water and decompose on heating or in the presence of acid, with the formation of nitrogen.
NH₄NO₂ → N₂ + 2 H₂O

Ammonium nitrite Standards and Recommendations

DOT Classification: Forbidden

Ammonium nitrite Specification

Ammonium nitrite (CAS NO.13446-48-5) is a kind of oxidants and it is high toxic. It may explode at a temperature of 60-70 °C. Ammonium nitrite (CAS NO.13446-48-5) also can be explosive when mixed with reducing agents, sulfur and phosphorus by heat, impact and friction. It also produce toxic fumes of nitrogen oxides and ammonia by heat. So the storage environment should be ventilate, low-temperature and dry. Keep Ammonium nitrite (CAS NO.13446-48-5) separate from organic matter, reducing agents, sulfur, phosphorus and combustible.
