What is Sodium Nitrite?

Sodium nitrite is an inorganic compound with the chemical formula NaNO2. It is a white to slightly yellowish crystalline powder, highly soluble in water and hygroscopic. From an industrial point of view, it is the most important nitrite salt. It is a precursor to various organic compounds such as pharmaceuticals, dyes and pesticides, while it is a food additive best known for its use in processed meats and fish products.

Sodium nitrite is toxic and overexposure can cause death in humans.

How is Sodium Nitrite produced?

The industrial production of sodium nitrite consists of one of two processes, such as reduction of nitrate salts or oxidation of lower nitrogen oxides.

One method uses molten sodium nitrate and oxidised lead as salt, while a more modern method uses scrap iron shavings to reduce nitrate.

A more commonly used method involves the general reaction of nitrogen oxides in alkaline aqueous solution with the addition of a catalyst. The exact conditions depend on which oxides of nitrogen are used and what the oxidant is, as conditions must be carefully controlled to avoid excessive oxidation of the nitrogen atom.

Sodium nitrite is also produced by the reduction of nitrate salts by exposure to heat, light, ionizing radiation, metals, hydrogen, and electrolytic reduction.

What does Sodium Nitrite look like?

Hygroscopic white to yellowish crystalline powder

What is the molecular formula of Sodium Nitrite?

Molecular Formula: NaNO2

In which sectors is Sodium Nitrite used?

  • rubber industry
  • metallurgical applications
  • Additive in industrial greases
  • cooling systems
  • Pharmaceuticals – cyanide poisoning
  • Food industry spoilage, colorant, preservative

What are the usage areas (processes) of Sodium Nitrite?

  • The main use of sodium nitrite is for the industrial production of organonitrogen compounds. It is the reagent for the conversion of amines to diazo compounds, which are the basic precursors of many dyes, such as diazo dyes. Nitroso compounds are produced from nitrites. These are used in the rubber industry.
  • It is used in various metallurgical applications for phosphating and detination.
  • Sodium nitrite is an effective corrosion inhibitor and is used as an additive in industrial greases.
  • Sodium nitrite is used as an aqueous solution and as a molten heat transfer medium in closed-loop cooling systems.
  • Sodium nitrite is an effective remedy in case of cyanide poisoning. It is used together with sodium thiosulfate. It is on the World Health Organization's List of Essential Medicines.
  • Sodium nitrite is used to accelerate the curing of meat and also to impart a pink color to meat.
  • It is used in the meat packaging industry to prevent spoilage and microbial growth.
  • It ensures that the taste of the packaged meat preserves its freshness for a long time.
  • Nitrite has the E number E250. Potassium nitrite (E249) is also used in the same way.
