Applications

Sodium nitrite is used in many industrial applications viz. in meat curing, coloring and preserving. It is used as a reagent in analytical chemistry, an antidote in cyanide poisoning, an electrolyte in electrochemical grinding, as a cooling solution in closed loop systems and as an additive in industrial greases. It finds application as a corrosion inhibitor as well as in the rubber industry. In metallurgy, it is used for phosphatizing and detinning. It acts as a precursor to diazo dyes, nitroso compounds and various organic compounds like pharmaceuticals. As a food additive, it is used to prevent botulism.

Notes

Decomposes above 320°. Hygroscopic. Incompatible with reducing agents, strong oxidizing agents, organics, finely powdered metals.
