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 Peroxybenzoate, a peroxyester, is a strong free radical source containing more than 8.1% of active oxygen; used as a polymerization initiator, catalyst and vulcanizing agent, crosslinking agent and as a chemical intermediate. The half-life temperatures are 102 C (for 10 hours), 124 C (1 for 1 hour) and 171 C (for 1 minute). 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 (< 30 C recommended or 38 C max) area and to keep away from reducing agents and incompatible substances.
