Sodium persulfate

Chemical properties

White, crystalline powder. Soluble in water; decomposed by alcohol; decomposes in moist air.

The Uses of Sodium persulfate

Bleaching and oxidizing agent; promoter for emulsion polymerization reactions.

The Uses of Sodium persulfate

Sodium peroxydisulfate is used as a radical initiator for emulsion polymerization reactions like acrylonitrile butadiene styrene, detergent component, soil conditioner and soil remediation. It is also used for curing of formaldehyde adhesives. It acts as a bleaching agent and in the production of dyestuffs. It finds application in zinc and printed circuit boards and considered to be a replacement for ammonium persulfate in etching mixtures. Further, it is used in the preparation of diapocynin from apocynin. It plays a role in the conversion of phenols to para-diphenols in alkaline solution and of arylamines to aminophenols. It is actively involved in the Elbs persulfate oxidation and the Boyland-Sims oxidation reactions as an oxidizing agent.

The Uses of Sodium persulfate

Redi-Dri^? is an innovative packaging product line that helps eliminate clumping material by adding extra packaging process steps without any chemical additives, anti-clumping agents, or hydrophobic compounds. Redi-Dri^? offers a more convenient and safer way to handle the products.

What are the applications of Application

Sodium persulfate is a strongly oxidizing chemical used as a bleaching and oxidizing agent

General Description

A white crystalline solid. Very irritating to skin and eyes. May be toxic by skin absorption. Used as a bleaching agent.

Air & Water Reactions

Water soluble. Decomposes slowly in moist air.

Reactivity Profile

Sodium persulfate is a strong oxidizing agent. Reacts with many combustible materials and reducing agents, often vigorously enough to start fires or cause explosions [Handling Chemicals Safely 1980 p. 855]. Decomposes gradually under ordinary conditions decomposition is promoted by moisture and heat [Merck]. Decomposed by alcohol and silver ions [Merck].

Hazard

By ingestion, strong irritant to tissue.

Health Hazard

Inhalation, ingestion or contact (skin, eyes) with vapors or substance may cause severe injury, burns or death. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may cause pollution.

Fire Hazard

These substances will accelerate burning when involved in a fire. Some may decompose explosively when heated or involved in a fire. May explode from heat or contamination. Some will react explosively with hydrocarbons (fuels). May ignite combustibles (wood, paper, oil, clothing, etc.). Containers may explode when heated. Runoff may create fire or explosion hazard.

Flammability and Explosibility

Non flammable

Safety Profile

Poison by intraperitoneal and intravenous routes. A powerful oxidizer; can cause fires. When heated to decomposition it emits toxic fumes of SOx and Na2O. See also SULFATES.
