Ammonium peroxidisulfate

Ammonium Peroxydisulfate is a strong oxidizing agent used in chemistry and biochemistry primarily as an initiator for polymerization reactions and as a reagent in analytical chemistry.

🏭⚗️ Production
Ammonium peroxydisulfate is synthesized by the electrolysis of a cold, concentrated solution of ammonium sulfate or ammonium bisulfate in sulfuric acid under controlled conditions. The resulting crystalline solid is collected, purified, and dried before being stored in airtight containers away from moisture and light.

🔬 Properties
Ammonium peroxydisulfate appears as a white crystalline powder with strong oxidizing properties. It is soluble in water, decomposes upon heating to release oxygen and sulfur oxides, and is sensitive to reducing agents and organic materials. It remains stable when stored in a cool, dry place away from incompatible substances.

🧪 Applications
This compound is widely used as a radical initiator in polymerization of monomers such as acrylates and styrene, in etching copper for printed circuit boards, and as an oxidizing agent in chemical synthesis and laboratory analyses.

⚠️ Safety
Handle with caution; ammonium peroxydisulfate is a strong oxidizer and can cause skin and eye irritation or burns. It may cause respiratory sensitization upon inhalation. Use gloves, eye protection, and work in a well-ventilated area. Keep away from combustible materials and reducing agents. Dispose of waste according to local chemical safety regulations.
