Granular sodium nitrite

1,Name: Sodium nitrite

　　Molecular formula: NaNO₂

　　Formula weght:69.00

2,Property:
　　(1) ordinary sodium nitrite: white little crystals or light yellow
　　(2) dry powder sodium nitrate: white crystal,non-caking, showing loose status.

　　Density:2.168. No odor, slightly salty. It is liable to deliquesce, dissolved in water,
　　soluble in liquid ammonia,slightly soluble in ethanol and glycerin,Melting Point:271℃. Decomposition temperature is
　　320℃，It has oxidability and also has reducibility. It will slowly be oxidized into sodium nitrate in atmosphere, it can 　　form nitrogen compound with nitrilo at low temperature.

3,Usage:

　　It has been widely used in making nitro-compound and azo dye, mordant of textile dyeing, bleaching agent, metal heat 　　finishing agent, cement early strength agent, and deicing agent etc.

Note:
　　① The product should be stored in a cool, dry place to prevent it from moisture, heat and sunlight. ② This product can
　　not be mixed with strong reductant, inflammable and explosive materials, food, feed and additives. ③ This product is
　　toxic and should be properly kept and can not be eaten.
