The potassium sulfate method uses ammonium sulfate and sulfuric acid to prepare an electrolyte for electrolysis after removing impurities. HSO4 is discharged at the anode to produce persulfate, and then reacts with ammonium sulfate to produce ammonium persulfate, then potassium sulfate is added for double decomposition reaction, and the finished product of potassium persulfate is prepared through cooling, separation, crystallization and drying. his
Anode reaction: 2hso4-2e → h2s2o8
Cathode reaction: 2h + 2e → H2 ↑
It is obtained by double decomposition reaction of ammonium persulfate and potassium sulfate, cooling, separation, crystallization and drying.
Application of potassium persulfate
Potassium persulfate can be used as gel breaker for oil well fracturing fluid. In the synthetic resin and synthetic rubber industry, it is used as initiator of emulsion polymerization for the synthesis of butadiene styrene rubber. Used as a remover of sodium thiosulfate in the photographic industry; Used as oxidant in dye and printing and dyeing industry; Used as bleaching agent in oil industry.
Precautions for potassium persulfate
Precautions for operation: close operation and strengthen ventilation. Operators must receive special training and strictly abide by the operating procedures. It is recommended that operators wear hooded electric air supply filter dust respirator, polyethylene anti-virus clothing and rubber gloves. Keep away from kindling and heat sources. Smoking is strictly prohibited in the workplace. Avoid dust generation. Avoid contact with reducing agent, active metal powder, alkali and alcohol. Handle with care to prevent damage to packaging and containers. Vibration, impact and friction are prohibited. Provide corresponding varieties and quantities of fire-fighting equipment and leakage emergency treatment equipment. Emptied containers may leave harmful substances.
Storage precautions: store in a cool, dry and well ventilated warehouse. Keep away from fire and heat source. Packing and sealing. It shall be stored separately from reducing agent, active metal powder, alkali, alcohol, etc., and mixed storage shall not be allowed. The storage area shall be provided with suitable materials to contain leakage.
