Sodium Nitrite NANO2 UN 1500 Nitrite Salt 99% With CAS No. 7632-00-0
Sodium nitrite is colorless to pale yellow orthorhombic prisms. Industrial products are white or slightly yellowish crystals. The density is 2.168g/cm3. The melting point is 271°C. Easily soluble in water and liquid ammonia. Slightly soluble in methanol, absolute ethanol and ether. Its aqueous solution is alkaline. The dew is slowly oxidized into sodium nitrate in the air. When heated to above 320°C, oxygen and nitrogen oxides are released. It is easy to burn and explode in contact with organic matter. poisonous.

Sodium nitrite is mainly used for diazotization reaction and as a preservative in food processing. Metal has anti-corrosion, anti-rust, and corrosion-inhibiting effects. Sodium nitrite can form a dense black oxide film on the surface of the metal to isolate the air and play a role in anti-corrosion. Used in dyes, medicine, printing and dyeing, bleaching, etc. Because of its color enhancement, antibacterial and antiseptic effects, it is used as a color additive for cooked meat.
