Sodium Percarbonate CAS 15630‑89‑4

Sodium percarbonate is referred to as SPC, commonly known as solid hydrogen peroxide, also known as sodium peroxycarbonate and solid hydrogen peroxide, which is an additive compound of hydrogen peroxide and sodium carbonate, which decomposes to produce oxygen, water and sodium carbonate. Sodium percarbonate not only has the function of liquid hydrogen peroxide, but also quickly decomposes and releases oxygen at lower water temperatures, realizing the functions of bleaching, decontamination, sterilization and odor removal. It is widely used in washing, printing and dyeing, textile, papermaking, medicine and hygiene, household and personal care formulation and other fields.

Preparation method: Dry production process – sodium peroxide crystals are prepared by spraying hydrogen peroxide solution on anhydrous sodium carbonate on a fluid bed with hot air boiling. Although the production process of this method is simple, it is rarely used in industry due to poor product stability, low reactive oxygen content, strict production technology and process conditions, and difficult operation. Wet production process – react the aqueous hydrogen peroxide solution with sodium carbonate in the presence of stabilizer, control the reaction temperature below 5 °C, and then add salt precipitant to make sodium peroxycarbonate crystallized, separated by centrifugation, and dried by air flow, that is, the finished sodium peroxycarbonate is obtained. The products produced by this method have good stability, mature technology, and are widely used in industry. At present, there are spray methods, low-temperature crystallization and solvent methods for production.
