High-Purity Sodium Nitrite from China Suppliers - Excellence in Quality from Our Factory

The production of sodium nitrite involves two key steps: ammonia oxidation and sodium nitrite formation, making it a pivotal process for many industries, **Ammonia Oxidation:**, In China, leading suppliers utilize advanced reactor systems, such as tank or tower reactors, to facilitate the reaction between ammonia gas and air. This process, which produces nitrous acid, relies on copper- or iron-based catalysts. Effective temperature, pressure, and gas flow control are crucial within the reactor to ensure optimal reaction efficiency. The resulting nitrous acid is then mixed with water, creating a nitrous acid solution that lays the foundation for further processing, **Sodium Nitrite Formation:**, Next, the nitrous acid solution reacts with sodium bicarbonate or soda ash (sodium carbonate) to create solid sodium nitrite. This critical step demands meticulous regulation of temperature, pH, and reaction time to ensure high-quality output. Once the reaction is complete, the final solid sodium nitrite product undergoes a thorough purification process, including filtration and drying, before packaging. As a trusted factory in China, we pride ourselves on delivering high-quality sodium nitrite to meet the demands of various industries
