Product Name: Sodium Nitrite

Cas No.: 7632-00-0

Chemical Formula: NNaO2

Executive Standard:GB 2367-2006

PRODUCT DESCRIPTION

Sodium nitrite (NaNO2), which is combined to generate the nitrite ion and sodium ion of inorganic salt. Sodium nitrite is easy to be delirized and soluble in water and liquid ammonia. Its aqueous solution is alkaline and slightly soluble in organic solvents such as ethanol, methanol and diethyl ether. Sodium nitrite has a salty taste and is sometimes used to make fake salt. Sodium nitrite reacts with oxygen to form sodium nitrate when exposed to air. If it is heated to above 320ºC, it will decompose and produce oxygen, nitrogen oxide and sodium oxide. Combustible and explode easily in contact with organic matter.

PRODUCT FEATURES

White little crystals or light yellow

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：271ºC. Decomposition temperature is 320ºC,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.
