Sodium Nitrite
Property
White or light yellow fine crystal. The relative molecular weight is 69.0 and density is 2.168. With a little saline taste, easy to be deliquescence and dissolve in water. The melting point is 271°C and decomposition temperature is 320°C. It has the strong oxidizing property, as well as reducing property. It can slowly oxidize into sodium nitrate in the air, and will become diamino compound composed with ammonia under low temperature.
Application
The main use of sodium nitrite is for the industrial production of organonitrogen compounds. It is a reagent for conversion of amines intodiazo compounds, which are key precursors to many dyes, such as diazo dyes. Nitroso compounds are produced from nitrites. These are used in the rubber industry.
