the above information is edited by the chemicalbook of wang xiaodong.
half-life 80℃-1.5 hours; 70℃-7.7 hours; 60℃-33 hours; 45℃-292 hours; 35℃-1600 hours.
recrystallization potassium persulfate dissolves in 30℃ water, cools, then the recrystallized product can be obtained, it is filtered and dried under reduced pressure in the presence of calcium chloride.

2. it is used for oxidative degradation of harmful substances in pool and closed circular loop in water.
3. it can be applied in the production of starch modifier and applied in the production of adhesive and coating agent.
4. it can be applied in the branched-chain oxidation, alcohol and aromatic hydroxy oxidation.
5. it is one of the basic constituent of hair dyes, it plays the role of decolorization.
toxicity the amount is not specified (fao / who, 2001).
potassium persulfate powder has stimulating effect on nasal mucosa, packaging should be ventilated to prevent dust. labour protection appliance should be dressed at work.
storage precautions potassium persulfate is non-flammable, it is combustion-supporting which due to it can release of oxygen, storage environment must be dry and clean, well-ventilated. pay attention to moisture and rain, it should not be transported in rain. keep away from fire, heat and direct sunlight. it should be kept sealed packaging, labels should be intact and clear. it should be stored separately with flammable or combustible materials, organic compounds, as well as rust, small amount of metal, and other reducing substance, it should avoid mix to prevent causing decomposition of potassium persulfate and explosion.
chemical properties it is colorless or white triclinic crystalline powder. it is soluble in water, the solubility is 1.75g / 100ml water at 0℃, the solubility is 5.3g / 100ml water at 20℃. it is insoluble in alcohol. queous solution is acidic.

it is mainly used as a disinfectant and fabric bleach. it can be used as industrial oxidant in dyes and inorganic salts. it can be used as emulsion polymerization initiators in synthetic rubber industry. it can be used as polymerization accelerator in synthetic resin. in addition, it can also be used in the steel, photographic industry and medicine.
it can be used as analytical reagents, oxidants and plastic initiator, it can also be used in the film photofinishing.
the above information is edited by the chemicalbook of wang xiaodong.
production method potassium sulfate method
ammonium sulfate and sulfuric acid formulates to form liquid electrolyte, it is decontaminated by electrolysis, hso4- can discharge and generate peroxydisulfate acidat in the anode, and then reacts with ammonium sulfate to generate ammonium persulfate, then replacement reaction can happen when potassium is added . the finished product of potassium persulfate can be obtained after cooling, separation, crystallization, drying.
anode reaction: 2hso4-2e → h2s2o8
cathodic reaction: 2h ++ 2e → h2 ↑
(nh4) 2so4 + h2s2o8 → (nh4) 2s2o8 + h2so4
(nh4) 2s2o8 + k2so4 + h2so4 → k2s2o8 + 2nh4hso4
it can be derived by replacement reaction with ammonium persulfate potassium sulfate, then it goes through cooling, separation, crystallization, drying.
category oxidant
toxicity grading mid toxicity.
acute toxicity oral - rat ld50: 802 mg / kg.
explosive hazardous characteristics it can explode when mixes with reductant, sulfur, phosphorus; it can explode when be heated, impacted, and meets fire.
chemical properties colourless odourless crystals or white powder
flammability hazard characteristic thermal decomposition can get oxygen; toxic fumes of nitrogen oxides can generate after combustion.
storage characteristics treasury should have ventilation and be low-temperature drying; loading and unloading should be light; it should be stored separately with organic matter, reducing agents, sulfur, phosphorus combustibles.
extinguishing agent mist of water, sand, foam.
professional standards twa 2 mg / m.
general description a white crystalline solid. specific gravity 2.477. decomposes below 100°c.
air & water reactions water soluble. slowly decomposed by water. the salt rapidly liberates oxygen when heated, and especially so when wet.
reactivity profile potassium persulfate is an oxidizing agent. noncombustible but accelerates the burning of combustible material. potassium persulfate plus a little potassium hydroxide and water released sufficient heat and oxygen to ignite a polythene (polyethylene) liner in a container. [mca case history 1155. 1955].
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.
