Sodium persulfate, also known as sodium persulfate, is an inorganic compound, the chemical formula Na2S2O8, is a white crystalline powder, soluble in water, insoluble in ethanol, mainly used as bleach, oxidant, emulsion polymerization accelerator.
Properties: White crystal or crystalline powder. No smell. Tasteless. Molecular formula Na2S2O8, molecular weight 238.13. It is gradually decomposed at room temperature, and can be rapidly decomposed by heating or in ethanol, after which oxygen is released and sodium pyrosulfate is formed. Moisture and platinum black, silver, lead, iron, copper, magnesium, nickel, manganese and other metal ions or their alloys can promote decomposition, high temperature (about 200℃) rapid decomposition, release hydrogen peroxide. Soluble in water (70.4 at 20℃). It is highly oxidizing. Strong irritation to the skin, long-term contact with the skin, can cause allergies, should pay attention to the operation. Rat transoral LD50895mg/kg. Store tightly. The laboratory produces sodium persulfate by heating a solution of ammonium persulfate with caustic soda or sodium carbonate to remove ammonia and carbon dioxide.
Strong oxidizing agent: Sodium persulfate has strong oxidation, can be used as an oxidizing agent, can oxidize Cr3+, Mn2+, etc. into the corresponding high oxidation state compounds, when there is Ag+, can promote the above oxidation reaction; It can be used as bleaching agent, metal surface treatment agent and chemical reagent by its oxidation property. Pharmaceutical raw materials; Accelerators and initiators for battery and emulsion polymerization reactions.
Application：Sodium persulfate finds extensive use as a bleach, oxidant, and emulsion polymerization accelerator. Its ability to remove stains and whiten fabrics has earned it a renowned reputation as a bleaching agent. Whether it’s stubborn wine stains on your favorite shirt or discolored linens, sodium persulfate can effortlessly tackle these issues.
Furthermore, sodium persulfate showcases potent oxidizing properties. This makes it ideal for aiding in chemical reactions that require the removal of electrons. In industries that rely heavily on oxidation processes, such as the production of pharmaceuticals and dyes, sodium persulfate proves to be an invaluable asset.
Additionally, this compound also serves as an emulsion polymerization promoter. For those unfamiliar with the term, emulsion polymerization refers to the process of synthesizing polymers in an aqueous medium. Sodium persulfate acts as a catalyst, assisting in the formation of these polymers. Industries utilizing emulsion polymerization, such as adhesives and coatings, heavily rely on sodium persulfate for its effectiveness in achieving desired outcomes.
The multifaceted nature of sodium persulfate is what sets it apart from other compounds. Its ability to function as both a bleaching agent and an oxidant makes it an attractive option for a wide range of industries. Additionally, its emulsion polymerization promoting properties further broaden its scope of application.
Besides its varied uses, sodium persulfate boasts several other distinguishing features. Its water solubility enhances its efficacy as a bleach and oxidant, allowing it to readily dissolve and interact with other substances. On the other hand, its insolubility in ethanol prevents it from interfering with processes that rely on ethanol as a solvent.
To ensure optimal usage of sodium persulfate, it is imperative to consider certain factors. Careful handling and adherence to safety guidelines are essential due to its potentially hazardous nature. Furthermore, appropriate dosage is crucial when incorporating sodium persulfate into any process, be it bleaching, oxidation, or emulsion polymerization.
