Liquid ammonia (liquid ammonia) refers to the liquid ammonia, the main storage form of industrial ammonia, the molecular formula is still NH3

Liquid ammonia is a commonly used non-aqueous solvent and refrigerant, and is the most commonly used inorganic solvent besides water. However, due to its volatile and corrosive nature, liquid ammonia is also prone to accidents during storage and transportation.

Liquid ammonia is a common inorganic non-aqueous solvent and is also used as a refrigerant and raw material for industrial production. It is used in the production of fertilizers, explosives, plastics and chemical fibers. Metal-liquid ammonia solutions have strong reducing properties and are widely used in inorganic and organic synthesis, often for the synthesis of transition metal compounds with low oxidation states. In organic chemistry, a sodium-liquid ammonia solution is used in the Birch reduction reaction to reduce an aromatic ring to a cyclohexadiene ring system. Liquid ammonia solutions of sodium or other metals can also reduce acetylene to produce trans-alkenes. In the chemical industry, liquid ammonia is one of the raw materials for urea production.
