High-Purity Sodium Nitrite from China Suppliers: Quality Production at Our Factory

The production of sodium nitrite in China is a meticulously controlled process involving two primary stages: ammonia oxidation and sodium nitrite formation, In the first stage, ammonia oxidation, ammonia gas is combined with air under precisely controlled conditions to generate nitrous acid. This critical step utilizes a reactor—often a tank or tower reactor—along with a copper- or iron-based catalyst to facilitate the reaction. Proper management of temperature, pressure, and gas flow rate within the reactor is imperative for optimal reaction efficiency. The resulting nitrous acid is then mixed with water in the reactor, creating a nitrous acid solution, The second stage involves sodium nitrite formation, where the nitrous acid solution reacts with sodium bicarbonate or soda ash (sodium carbonate) to yield solid sodium nitrite. This phase demands exacting control over temperature, pH, and reaction time to ensure a high-quality product. Once the reaction concludes, the solid sodium nitrite undergoes purification and packaging through processes such as filtration and drying, As a reputable sodium nitrite factory and supplier in China, we are committed to providing high-quality products through our efficient production methods
