APPLICATIONS

Peroxide: Compound containing the peroxy group (-O-O-), chainlike structure, containing two oxygen atoms, each of which is bonded to the other and to a radical or some element. It is considered that hydrogen peroxide is the starting material to prepare organic and inorganic peroxides commercially. Hydrogen Peroxide H2O2, is a powerful oxidizing agent. The most valuable property of hydrogen peroxide is that it breaks down into water and oxygen and therefore does not form any persistent, toxic residual compounds. It is used in the processes of epoxidation, oxidation, hydroxylation and reduction. Its oxidizing properties are used in the bleachings and deodorizing for textile, hair and in paper manufacture. It is also used medicinally as an antiseptic.  Its application involves the production of chemicals like perhydrates as well as organic peroxides in which some organic (or inorganic) substituents have replaced one or both hydrogens. Some metals form peroxides in air sodium, barium or zinc. Metal peroxide releases oxygen slowly in contact with atmospheric moisture and used to as disinfectants in cosmetics, detergents, toothpaste and pharmaceuticals. They can be used in the bleachings and deodorizing and a oxygen release source in agricultural application to generate contaminated soils and lakes. Organic Peroxides are powerful oxidizing agents releasing oxygen. They are widely used as initiators,catalysts and crosslinking agent for the polymerization process in the plastics manufacturing industry and as chemical intermediates, bleaching agents, drying and cleaning agents. They are also used as antiseptics, disinfectants and germicides medically for cosmetics, detergents, toothpaste and pharmaceuticals. Organic peroxides are classified in peroxydicarbonates, peroxyketals, peroxyesters, ketone peroxides, hydroperoxides, dialkyl peroxides, diacyl peroxides by HMIS.

Tert-Butyl Hydroperoxide has a high thermal stability compared to other organic peroxides and is one of the safest organic peroxides. It decomposes rapidly, causing fire and explosion hazard, on heating and under influence of light. It reacts violently with incompatible substances or ignition sources (acids, bases, reducing agents, and heavy metals). It should be stored in a dry and refrigerated (< 27C recommended or 38 C max) area and to keep away from reducing agents and incompatible substances. It is sold commonly as a dilution containing 69-70 w/w% in water. It is soluble in the most solvents hydrocarbon solvents as well as in water. This solubility makes it a versatile oxidation agent for selective aqueous or non-aqueous oxidations. It is used as a free radical initiator over a wide temperature range under appropriate redox initiation. TBHP is one of the general cationic or curing agent for emulsion and suspension polymerization of ethylene, vinylacetate, acrylates. PVC, unsaturated polyesters. The one of main application of TBHP is the source of tertiary-butyl derivatives including peresters, perketals, and alkyl peroxides. TBHP undergoes epoxidation reaction of alpha-olefins in the presence of various choice of transition metal catalysts. The choice of metal catalysts is important to control selectively reactivity and to minimize side reactions and to determine chemo-, regio-, and stereoselectivity. It is an useful selective oxidation source in presence of transition metal catalysts. It oxidizes sulfur compounds to soluble derivatives to be removed in petroleum refinery. It is used as an additive in lubricants to reduce the wear of metal the surfaces. It is also used in bleaching, waste treatment and disinfectant.
