Physical and Chemical Properties | The active substance of the potassium persulfate complex salt is potassium persulfate KHSO5 (or known as potassium peroxymonosulfate). It has a very strong and effective non-chlorine oxidation ability, and the use and treatment process meets the requirements of safety and environmental protection. Therefore, it is widely used in industrial production and consumption. In general, it is relatively stable, and the decomposition reaction is easy to occur when the temperature is higher than 65. More active, easy to participate in a variety of chemical reactions, can be used as oxidants, bleaching agents, catalysts, disinfectants, Etchants, etc. |
Use | Used for oral cleaning, swimming pool and hot spring water Disinfection, pulp bleaching |

Introduction | potassium persulfate refers to potassium bisulfate complex salt, which is an inorganic acidic oxidant. Potassium persulfate compound salt is a new type of active oxygen Disinfection agent, as the fifth generation Disinfection agent, has a very strong and effective non-chlorine oxidation ability, its aqueous solution is acidic, very suitable for all kinds of water Disinfection, after dissolution, a variety of highly active small molecule free radicals, active oxygen and other derivatives are produced, and toxic by-products are not formed in water, and the safety is extremely high. |
sterilization principle | potassium monopersulfate is very similar to peracetic acid, and peroxygen bond is connected with sulfur atom and carbon atom respectively, potassium persulfate is an inorganic substance, and Disinfection of its active ingredient is monopersulfate ion, which oxidizes the proteins of microorganisms, leading to the death of microorganisms. Potassium monopersulfate is a neutral salt, and the acidity of its aqueous solution is caused by the dissolution of potassium hydrogen sulfate in the complex salt to produce hydrogen ions. However, the stability of potassium hydrogen sulfate in acidic conditions is much better than that in neutral conditions, and it will decompose rapidly under alkaline conditions. The compound potassium persulfate compound salt is a potassium monopersulfate compound salt disinfectant made of sodium chloride, organic acid and potassium monopersulfate. In aqueous solution, the chain reaction occurs in water by using the special oxidation ability of potassium monopersulfate, continuously produce new ecological oxygen, hypochlorous acid, free hydroxyl, hydrogen peroxide. Through the new ecological oxygen and free hydroxyl oxidation can change the permeability of the cell membrane to break, so that the normal protective layer, to kill bacteria, fungi, protozoa, Virus of the purpose. |
Application | pharmaceutical/chemical synthesis is the basic raw material for the preparation of Dioxirasnes series catalysts such as DMD and TFD, with its mild reaction conditions, efficient oxidation activity and excellent selectivity, peroxyketone has opened up a new path for asymmetric reaction and natural drug synthesis. In the design of the olefin asymmetric reaction catalyst, the chiral amine, the chiral imine salt polymerization initiator, the polymerization of vinyl acetate, ethyl acrylate and acrylonitrile, the polymerization of vinyl monomer, the binder and the blending agent can be in situ oxidized. |
