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