High-Purity Sodium Nitrite from China Suppliers - Factory Direct Excellence and Quality

Sodium nitrite production involves two critical steps: ammonia oxidation and sodium nitrite formation, Ammonia oxidation is the first stage, where ammonia gas reacts with air under controlled conditions to generate nitrous acid. This process takes place in a reactor—such as a tank or tower reactor—utilizing a copper- or iron-based catalyst. It is vital to maintain strict control over temperature, pressure, and gas flow rates within the reactor to ensure a smooth reaction. The nitrous acid produced is then dissolved in water to create a nitrous acid solution, The second step is sodium nitrite formation. In this phase, the nitrous acid solution is combined with sodium bicarbonate or soda ash (sodium carbonate), resulting in solid sodium nitrite. This step involves precise temperature, pH, and timing control to achieve optimal results. Once the reaction is complete, the solid sodium nitrite undergoes purification and packaging through processes such as filtration and drying, As a leading factory in China, we are committed to providing high-quality sodium nitrite.
