Potassium Persulfate
Potassium persulfate is the inorganic compound with the formula K2S2O8. It is the potassium salt of persulfate (also called peroxydisulfate), an oxidizer. It is a white solid that dissolves in water. It is almost non-hygroscopic and has good shelf-life. Persulfate is often used as a strong oxidizer or monomer polymerization initiator.

Potassium persulfate is but only an initiator for latex or acrylic monomer polymer fluid, vinyl acetate or chloroethylene, etc. but also an initiator for the copolymerization of cinnamene, acrylonitrile, butadiene and other colloids. It is often used as a strong oxidizer and has the following usages

(1) Used while rinsing or cleaning the surface of metal with acid;
(2) Accelerate the processing procedure of low concentration formalin binder;
(3) Used as a regulator while producing amylum and applied to the production of binder or paint;
(4) Used as desizing agent or active bleaching agent;
(5) For hair dye, as a principal ingredient with discoloring function.
(6) Used as oxidizer for remediation of envionmental protection.

Potassium persulfate is the inorganic compound with the formula K2S2O8. Also known as potassium peroxydisulfate or KPS, it is a white solid that is sparingly soluble in cold water, but dissolves better in warm water. 
This salt is a powerful oxidant, commonly used to initiate polymerizations.

Potassium persulfate can be prepared by electrolysis of a cold solution potassium bisulfate in sulfuric acid at a high current density.[1]

2 KHSO4 → K2S2O8 + H2
It can also be prepared by adding potassium bisulfate (KHSO4) to a solution of the more soluble salt ammonium peroxydisulfate (NH4)2S2O8. In principle it can be prepared by chemical oxidation of potassium sulfate using fluorine.

This salt is used to initiate polymerization of various alkenes leading to commercially important polymers such as styrene-butadiene rubber and polytetrafluoroethylene and related materials. In solution, the dianion dissociates to give radicals:[3]

[O3SO-OSO3]2− ⇌ 2 [SO4]•−
It is used in organic chemistry as an oxidizing agent,[4] for instance in the Elbs persulfate oxidation of phenols and the Boyland–Sims oxidation of anilines.

As a strong yet stable bleaching agent it also finds use in various hair bleaches and lighteners. Such brief and non-continuous use is normally hazard free, however prolonged contact can cause skin irritation.[5] It has been used as an improving agent for flour with the E number E922, although it is no longer approved for this use within the EU.

The salt is a strong oxidant and is incompatible with organic compounds. Prolonged skin contact can result in irritation.

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].

Strong irritant and oxidizing agent. Fire risk in contact with organic materials.

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.

Agricultural Uses
Potassium sulphate, also called sulphate of potash, is a white crystalline material, moderately hygroscopic, available in fine, granular and semi-granular forms. It contains 48 to 54% potassium (as K2O) and supplies 17 to 20 % of sulphate. Chloride-sensitive crops like tobacco, grapes and potato require chloride-free potassium fertilizers. Therefore, these crops are fertilized with potassium sulphate, although this is more expensive than potassium chloride. These three crops, being major crops, account for about 7% of the total potash consumption. For best results, potassium sulphate should contain at least 50 % potash by weight.
Potassium sulphate occurs in nature as 'langbeinite' , a double sulphate of potassium and magnesium (K2SO4?2MgSO4) and made from burkeite (Na2CO3?2Na2SO4), kainite (KCl?MgS04?3H2O) or potassium chloride (KCl) as follows:
When applied to soil, potassium ion from the watersoluble potassium sulphate is retained in the soil colloids and not easily leached out. This makes potassium sulphate an excellent fertilizer, useful for all soils and crops while sowing or before sowing. It is also a safe ingredient of powdered, mixed fertilizers.

Safety Profile
Moderately toxic by ingestion. An irritant and allergen. A powerful oxidtzer. Flammable when exposed to heat or by chemical reaction. Can react with reducing materials. It liberates oxygen above 100' when dry or @ about 50' when in solution. When heated to decomposition it emits highly toxic fumes of SOx,, S2O8, and K2O.

Potential Exposure
Potassium persulfate is used as a bleaching and oxidizing agent; it is used in redox polymeri- zation catalysts; in the defiberizing of wet strength paper and in the desizing of textiles. Soluble in water.

The need for increased stabilities and for controllable permeabilities and morphologies led to the development of polymerized surfactant vesicles [55, 158-161]. Vesicle-forming surfactants haw been functionalized by vinyl, methacrylate, diacetylene, isocyano, and styrene groups in their hydrocarbon chains or headgroups. Accordingly, SUVs could be polymerized in their bilayers or across their headgroups. In the latter case, either the outer or both the outer and inner surfaces could be polymerized separately (Fig. 38). Photopolymerization links both surfaces selective polymerization of the external SUV surface is accomplished by the addition of a water-soluble initiator (potassium persulfate, for example) to the vesicle solution. [Pg.55]

Polymerization of styrene in each of the three types of microemulsions was performed using a water soluble initiator, potassium persulfate (K2S208), as well as an oil-soluble initiator, AIBN. As desired, solid polymeric materials were obtained instead of latex particles. In the anionic system, the cosolvent 2-pentanol or butyl cellosolve separates out during polymerization. Three phases are always obtmned after polymerization. The solid polymer was obtained in the middle with excess phases at the top and bottom. GC analysis of the upper phase indicates more than 80% 2-pentanol, while Karl-Fisher analysis indicated more than 94% water in the lower phase. Some of the initial microemulsion systems have either an excess organic phase on top or an excess water phase as the bottom layer. GC analysis showed the organic phase to be rich in 2-pentanol. However, the volume of the excess phase is much less in the initial system than in the polymerized system. [Pg.72]

Most emulsion polymerization is based on free-radical reactions, involving monomers (e.g., styrene, butadiene, vinyl acetate, vinyl chloride, methacrylic acid, methyl methacrylate, acrylic acid, etc.), surfactant (sodium dodecyl diphenyloxide disulfonate), initiator (potassium persulfate), water (18.2MQ/cm), and other chemicals and reagents such as sodium hydrogen carbonate, toluene, eluent solution, sodium chloride, and sodium hydroxide. [Pg.864]

Emulsion polymerization of methyl methacrylate under the action of pulsed microwave irradiation was studied by Zhu et al. [11], The reactions were conducted in a self-designed single-mode microwave reaction apparatus with a frequency of 1250 MHz and a pulse width of 1.5 or 3.5 ps. The output peak pulse power, duty cycles, and mean output power were continuously adjustable within the ranges 20-350 kW, 0.1-0.2%, and 2-350 W, respectively. Temperature during microwave experiments was maintained by immersing the reaction flask in a thermostatted jacket with a thermostatic medium with little microwave absorption (for example tetrachloroethylene). In a typical experiment, 8.0 mL methyl methacrylate, 20 mL deionized water, and 0.2 g sodium dodecylsulfonate were transferred to a 100-mL reaction flask which was placed in the microwave cavity. When the temperature reached a preset temperature, 10 mL of an aqueous solution of the initiator (potassium persulfate) was added and the flask was exposed to microwave irradiation. [Pg.655]

In an in-situ encapsulation process, a dispersion including monomers and the pigment particles can be homogenized. The monomers in the dispersion are then polymerized at the surface of the pigment so as to encapsulate the pigment particles. 6-15% of the monomers are acidic. The acidic monomers can assist the pigment in remaining properly dispersed in the inkjet ink. As a polymerization initiator, potassium persulfate may be used (20). [Pg.129]

There are various additives in PVC plastics, such as antioxidants, light stabilizers, initiators, plasticizers, flame retardants, pigments and others. As initiators, potassium persulfate, benzoyl peroxide, lauryl peroxide, percarbonate and some azo-compounds can be used. The presence of chlorine in the hydrocarbon backbone gives rigidity and toughness to the polymer, but PVC liberates hydrogen chloride when exposed to high temperatures. To prevent this, stabilizers are added to the polymer. There are several kinds of stabilizers on the market. The most important contain lead, tin, calcium and zinc and... [Pg.608]

Cho and Lee used three different initiators, potassium persulfate, 2,2 -azobisisobutyronitrile, and 4,4 -azobis(4-cyanovaleric acid) (water-soluble, but less hydrophilic than potassium persulfate) to investigate their effects on the emulsion polymerization of styrene in the presence of polymethyl methacrylate seed latex particles. Inverted core/shell latex particles were observed when 2,2 -azobisisobutyronitrile or 4,4 -azobis(4-cyanovaleric acid) was used to initiate free radical polymerization. The use of potassium persulfate resulted in various morphological structures of latex particles, which were largely determined by the initiator concentration and polymerization temperature
