Chinese name: granular sodium nitrite
English name: Granular Sodium nitrite
CAS NO：7632-00-0
EC NO：231-555-9
UN：1500
Molecular formula: NaNO2
Molecular mass: 68.99
(1) General sodium nitrite: white fine crystal, or light yellow
(2) Dry powder sodium nitrite: white crystal, no agglomeration, loose, specific gravity 2.168, odorless, slightly salty, easy to deliquescence, easily soluble in water, melting point of 271 °C, decomposition temperature 320 °C, oxidation, and reduction. Slowly oxygen forms sodium nitrate in the air, and it is easy to form nitrogen compounds with amino groups at low temperatures.
It is mainly used as raw materials for the manufacture of nitro compounds, azo dyes, etc., mordants for fabric dyeing, bleaching agents, as well as metal heat treatment agents, cement premature strength agents and anti-icing agents.
1. This product should be stored in a cool and dry place to prevent moisture, heat and sun exposure.
2. This product shall not be mixed with strong reducing agents, flammable and explosive products, food, feed and additives.
3. This product is toxic, should be properly kept, do not eat by mistake.
GB/2367-2006
Performance characteristics:
Name: Sodium Nitrite

Quality:
(1) General sodium nitrite: white fine crystal, or light yellow
(2) Dry powder sodium nitrite: white crystal, no agglomeration, loose, specific gravity 2.168, odorless, slightly salty, easy to deliquescence, easily soluble in water, melting point of 271 °C,
The decomposition temperature is 320 °C, which is oxidizing and reductive. Slowly oxygen forms sodium nitrate in the air, and it is easy to form nitrogen compounds with amino groups at low temperatures.
Uses: mainly used as raw materials for the manufacture of nitro compounds, azo dyes, etc., mordants for fabric dyeing, bleaching agents, as well as metal heat treatment agents, cement early strength agents and anti-icing agents.
