Anti - Microbial Agents NaNO2 Sodium Nitrite
NaNO2 Sodium Nitrite Manufacture For Industry Use UN 1500 99% Min
Sodium nitrite is white or slightly yellow crystals, relative molecular mass of 69.0, specific gravity: 2.168, odorless, slightly salty, easily deliquescence, soluble in water, melting point of 271 °C, the decomposition temperature of 320 °C, with oxidation of both reduction. Slowly oxidized in air to nitrite, at low temperature the formation of a diazonium compound with an amino easily. Toxic!
Sodium Nitrite is mainly used as the raw material of productions of nitro compound and azo dyes, etc. Sodium Nitrite is also used as mordant and bleacher for fabric dyeing, as well as metal heat treatment agent, early-strength admixture and antifreeze of cement.
