Brief Overview

 

Sodium Nitrite is an inorganic compound with chemical formula NaNO2 and as the sodium salt of nitrous acid HNO2. It forms white to slight yellowish crystalline powder in the pure state. Sodium nitrate is hygroscopic and very soluble in water and aqueous ammonia. It can be found in nature in several vegetables, such as spinach, parsley, lettuce, broccoli, curly kale, and asparagus. It also can be found in the human body to control bacteria in the stomach and prevent gastroenteritis. Sodium nitrite is toxic and mutagenic. Produces very toxic carcinogenic nitrosamines on reaction with secondary or tertiary amines. Is is also used to treat cyanide poisoning. Sodium nitrite has some environmental effects and high doses can even lead to death.

 

 

Manufacturing process


The manufacturing process of sodium nitrite is by reacting sodium hydroxide with nitrogen dioxide and nitrogen monoxide. The product of this reaction is sodium nitrite and water. Sodium carbonate also can use as sodium hydroxide substitutes. The overall reaction of manufacturing sodium nitrite is shown below:

                                                2NaOH + NO2 + NO → 2NaNO2 + H2O

The manufacturing process of sodium nitrite comprises the steps of:

Absorption of nitrogen oxide in sodium hydroxide or sodium carbonate liquid

The nitrogen dioxide and nitrogen monoxide can be obtained from the manufacturing process of ammonia. It is preferable to use excess nitrogen oxide than nitrogen dioxide to increase the production of sodium nitrite and minimize the production of sodium nitrate. The absorption reaction of nitrogen dioxide and nitrogen monoxide in sodium hydroxide produce sodium nitrite solution.

Evaporation

Sodium nitrite solution that obtained then being cooled to crystallize. The product is suspensions that contain solid crystalline sodium nitrite in water. To increase the concentration, the suspension is being heated until containing water evaporated. The evaporation process separates crystalline sodium nitrite from the mother liquor.

 



Textile Industry

Sodium nitrite is used in dyeing and printing of textiles. It is used in the manufacture of azo dyes and for oxidizing dyeings and prints with leuco vat dyes. As a dyeing agent, it is used to make basic dye, acid dye, direct dye, sulfur dye, diazo and azoic dyes.
