Sodium nitrite is an inorganic chemical that is available as a pale-yellow crystalline powder. This substance is soluble in water and absorbs moisture.
It melts at a temperature of 271 degrees Celsius and decomposes into sodium oxide, nitrogen oxides and nitrogen at a temperature of 320 degrees Celsius.
This combination is available in the market in two edible and industrial grades. The industrial process of producing this substance relies on the conversion of liquid ammonia and the presence of sodium carbonate or sodium hydroxide.
Liquid ammonia is oxidized at high temperature in a catalytic bed in the presence of air and produces nitrogen oxides. Nitrogen oxides enter an absorption tower and react with sodium carbonate or sodium hydroxide solution to form sodium nitrite solution.
