Urea
hydrogen peroxide is
an unstable combination of urea and hydrogen
peroxide in equal amounts. It is soluble in water,
alcohol, and ethylene glycol. It decomposes
at 75-85 C or by moisture. is
used as a source of water-free hydrogen peroxide.
It is used in the bleachings and deodorizing for
fibers. It is used as a disinfectant in cosmetics,
detergents and pharmaceuticals. Its applications
include starch modification, color developer and
catalyst of organic synthesis.

| GENERAL
DESCRIPTION OF PEROXIDE |
| 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 include
peroxyacetic acid, benzoyl peroxide, cumyl and tert-butyl peroxides. |
