Chinese name： Industrial Sodium Nitrite (NaNO2)
English name：Sodium nitrite
CAS NO：7632-00-0
EC NO：231-555-9
UN：1500
Molecular formula： NaNO2
Molecular weight：68.99
White or a little buff fine crystal. The relative molecular weight is 69.0 and density is 2.168. It is unscented with a little saline taste, easy to be deliquescenced and to dissolve in water. The melting point is 271 land decomposition temperature is 320笆.It has property ofoxidability and reducibility. It can be slowly oxidized into sodium nitrite in the air, and become diamino compound composed with ammonia under low temperature.
It is mainly used as the production raw material of nitro-compound and azo dyes, etc. It is also used as mordant and bleacher for fabric dyeing, as well as metal heat treatment agent, early-strength admixture and antifreeze of cement.
