Applications of potassium persulfate Some of the main applications of this substance include use as a polymerization initiator, circuit cleaning and etching, copper and aluminum surface activation, modified starch, pulp and textile bleaching, and low-temperature descaling in circulating water purification systems. Water, oxidative destruction of harmful gases, low formaldehyde glue with the ability to stick together by accelerating the oxidation of ethanol and aromatic hydrocarbons, disinfectants, decolorization of hair color.
Uses of potassium persulfate
Polymerization and use as a catalyst
This salt is used to initiate the polymerization of various alkenes that lead to the production of commercially important polymers such as styrene-butadiene rubber and polytetrafluoroethylene and related materials. In solution, this compound separates the dianion and forms a radical.
It is used in organic chemistry as an oxidizing agent, for example in Elbs sulfate oxidation of phenols and Boyland-Sims oxidation of anilines.
Hair bleach and lightener
This material is also used as a strong bleaching agent and at the same time stable in all types of hair bleaches and lighteners. Such brief, non-continuous use is normally harmless, but prolonged contact can cause skin irritation. It is used as a flour improver under the number E922, although it is no longer approved for this use in the European Union.
Potassium persulfate is mainly used as strong oxidizing agents and stimulants. This substance is the initiator of latex or solution polymerization of acrylic monomers, vinyl acetate, vinyl chloride and other products, and it is also the initiator of styrene, acrylonitrile, butadiene and similar emulsions for polymerization.
Use in the flour industry
This material can be used as a wheat flour gluten agent.
Use in textile and dyeing industry
It is mainly used as a disinfectant and fabric bleach. It can be used as an industrial oxidant in paints and inorganic salts.
Use in synthetic rubber industry
This material can be used as emulsion polymerization initiators in the synthetic rubber industry.
Use in the resin industry
This compound can be used as a polymerization accelerator in synthetic resin.
Other uses of potassium persulfate
In addition, it can also be used in the photographic and medical steel industry. This substance can be used as an analytical reagent, oxidant and plastic stimulant, and it can also be used in film joinery.
Applications of potassium persulfate in agriculture
Potassium sulfate, which is also called potassium sulfate, contains 48 to 54% potassium and 17 to 20% sulfate. Chloride-sensitive crops such as tobacco, grapes, and potatoes require chloride-free potassium fertilizers. Therefore, these crops are fertilized with potassium sulfate, although this fertilizer is more expensive than potassium chloride.
When this compound is applied to the soil, the potassium ion from the water-soluble potassium sulfate is retained in the soil colloids and is not easily washed away. This makes potassium sulfate an excellent fertilizer that is beneficial to all soils and crops at or before planting.
Complications and dangers of potassium persulfate
Accidental ingestion of this substance may be harmful. Animal experiments show that consuming less than 150 grams may be fatal and cause serious damage to a person’s health.
There is evidence that this substance causes skin inflammation in a significant number of people. Skin irritation may also lead to a form of contact dermatitis (non-allergic) after prolonged or repeated exposure. Dermatitis is often characterized by redness of the skin (erythema), and the swelling may progress to blistering (vesiculation), scaling, and thickening of the epidermis.
This material may accentuate any previous dermatitis. Open cuts, abraded or irritated skin should not be exposed to this material. Its entry into the bloodstream through cuts, scrapes, puncture wounds, or lesions may cause systemic injury with deleterious effects. Before use, be sure to wear gloves and examine the skin to ensure that it is adequately protected from any external damage.
This substance may cause eye irritation in a significant number of people or may produce significant eye damage. Repeated or long-term eye contact may cause marked inflammation with temporary redness in the conjunctiva, temporary visual impairment or other premature eye damage.
Long-term exposure to respiratory irritants may lead to respiratory disease, which includes difficulty breathing and related systemic problems.
Practical evidence shows that inhalation of these substances causes an allergic reaction in a significant number of people. Pulmonary sensitivity as a result of airway dysfunction and pulmonary allergy may be accompanied by fatigue, lethargy and pain.
Long-term exposure to high concentrations of dust may cause changes in lung function (i.e. pneumoconiosis) caused by penetration of particles less than 0.5 microns and staying in the lung. Its main symptom is shortness of breath.
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 may also cause pollution.
Storage conditions for potassium persulfate
These materials accelerate the burning speed when they catch fire.
Some may decompose explosively when heated or in a fire, and may explode due to heat or contamination.
Some react explosively with hydrocarbon (fuel). This compound may ignite combustible materials (wood, paper, oil, clothing, etc.). Containers may explode when heated.
To maintain this material, note that it is not compatible with combustible, organic or other oxidizable materials.
Sulfur, metal dusts such as aluminum dust, chlorate and perchlorate are incompatible with this material and can attack chemically active metals due to their oxidizing properties. Keep potassium persulfate away from moisture and direct sunlight.
Potassium persulfate is a strong oxidizing chemical that is sold in the market as white (or colorless) crystals, white granules, and white powder with the formula k2s2o8. Other characteristics of potassium persulfate include salty and bitter taste, with a boiling point of 1689°C and a melting point of 1067°C.
Potassium persulfate is easily soluble in water but insoluble in ethanol. Its pH is between 5.5 and 8.5.
