Description

Potassium peroxymonosulfate sulfate is an inorganic compound, a granular crystalline powder, with a molecular formula of H3K5O18S4, a molecular weight of 346.29, a melting point of >70°C, a density of 1.12-1.20, and a water solubility of 250 G/L (20 ºC). Potassium peroxymonosulfate sulfate is a strong oxidizing agent, soluble in water, and acidic in water. It is stable in air, but decomposes at high temperatures to produce toxic gases such as sulfur dioxide and oxygen. It reacts with many other compounds, such as reducing agents and easily oxidizable substances. Potassium peroxymonosulfate sulfate is a stable, convenient, and widely used excellent acidic oxidant.

Potassium peroxymonosulfate sulfate (2KHSO5.KHSO4.K2SO4) Use and Manufacturing

Potassium peroxymonosulfate sulfate is usually prepared by the reaction of hydrogen peroxide and sulfuric acid. The specific steps are to slowly add hydrogen peroxide to dilute sulfuric acid, then adjust the temperature and reaction conditions of the solution so that the reaction is complete, and filter to produce Potassium peroxymonosulfate sulfate crystals. Potassium peroxymonosulfate sulfate is used to make dry laundry bleach, detergent bleach, and scouring powder, and is generally used only for cleaning wool and reducing wool shrinkage. It is used in industry to make other chemicals such as sodium persulfate and sodium persulfate bleaching powder. It is also used as a plastic dishwashing detergent and metal cleaner, a perm neutralizer.
