This product is manufactured using sulfur dioxide, concentrated sulfuric acid, and concentrated nitric acid as raw materials, through multi-stage absorption tower circulation absorption and drying processes. It is primarily used in diazotization reactions in the synthesis of dyes and pharmaceuticals. Nitrosyl sulfuric acid has strong oxidizing properties, corrosiveness, and undergoes violent exothermic reactions when in contact with water.
