Mulperoksiidsulfaat

Mulperoksiidsulfaat, in Dutch often referred to as multiperoxidesulfaat, denotes salts that contain the peroxydisulfate anion S2O8^2−. These compounds are part of the persulfate family and are recognized primarily for their strong oxidizing properties. Common examples include sodium persulfate (Na2S2O8) and potassium persulfate (K2S2O8).

The peroxydisulfate anion consists of two sulfate units connected by a peroxide (O–O) bridge. In aqueous solutions, mulperoksiidsulfaat salts act as powerful oxidizers and can decompose under heat or catalytic conditions to form sulfate-based radicals, driving various chemical reactions, including radical-initiated polymerizations.

Production and composition: Industrially, persulfate salts are typically produced by electrochemical oxidation of sulfate solutions, followed by crystallization of the desired salt (e.g., Na2S2O8, K2S2O8, or ammonium salts). Alternative chemical routes exist, but electrochemical methods are the primary large-scale approach for generating stable persulfate salts used in industry.

Applications: Mulperoksiidsulfaat salts serve as radical initiators in polymer chemistry, notably in the polymerization of acrylates and other monomers. They are also used as oxidizing agents in hair bleaching formulations, paper and textile processing, and certain cleaning or etching applications in electronics and metal finishing.

Safety: These salts are strong oxidizers and can cause exothermic reactions with reducing agents or organic materials. They may irritate skin, eyes, and the respiratory tract. Handling requires appropriate PPE, storage away from incompatible substances, and careful control of temperature and contamination.
