Sodium nitrite, chemical formula is NaNO2, white yellowish crystalline powder in appearence, is a kind of inorganic compound. Sodium nitrite slightly salty, easy deliquescence. Sodium nitrite is soluble in water, slightly soluble in ethanol, methanol, ether. Its aqueous solution is alkaline with a pH of about 9. The main use of sodium nitrite is to manufacture azo dyes, can also be used as fabric dyeing mordant, bleaching agent, metal thermal treatment agent.
Sodium nitrite reacts with oxygen to form sodium nitrate when exposed to air. Sodium nitrite can also be oxidized by strong oxidants, especially ammonium salts. For example, it can interact with ammonium nitrate, ammonium persulfate and so on at room temperature to produce high heat, causing combustible combustion. Sodium nitrite meets the weak acid decomposition gives off the brown nitrogen dioxide gas. Sodium nitrite breaks down when heated above 320 ° C to produce oxygen, nitrogen oxide and sodium oxide.
The main use of sodium nitrite is the industrial production of organic nitrogen compounds and food additives.
The main use of sodium nitrite is the industrial production of organic nitrogen compounds. It is a reagent that converts amines into diazo compounds, a key feedstock for many dyes.
Food-grade sodium nitrite is often used in meat curing. It is characterized by its ability to increase the freshness of meat, inhibit microorganisms, and help maintain the structure and nutritional value of meat products. However, sodium nitrite is a highly toxic substance in food additives, and the limit intake of human body is 0.3 G. If this limit is exceeded, it can cause sodium nitrite poisoning and even death. Therefore, sodium nitrite should be used as little as possible or not in food production.
PACKAGE & STORAGE
Sodium nitrite should be placed in low temperature, dry, ventilated warehouse. The storeroom should have closed doors and Windows to prevent direct sunlight. Sodium nitrite can be stored with other nitrates other than ammonium nitrate, but should be stored in isolation with organic matter, combustible materials, reducing agents, and isolated fire source.
