GENERAL
DESCRIPTION
|
|
Hydrogen
Peroxide is a is a strong oxidizing agent and a
weak acid in water solution. The formular is similar
to that of water, with an extra atom of oxygen attached,
H2O2. It is completely soluble in water. Pure anhydrous
hydrogen peroxide is a colorless to pale blue syrupy
liquid which decomposes violently into water and
oxygen if heated above 80 C. it also decomposes
in light and in the presence of metal ions or oxidizable
organic materials. A small amount of stabilizer
such as acetanilide is added to the solutions to
retard the decomposition. One volume of hydrogen
peroxide releases ten volumes of oxygen when it
decomposes. It is commercially prepared by electrolysis
of ammonium bisulfate or potassium bisulfate with
sulfuric acid. Catalytic oxidation of hydrogen and
water with oxygen using nickel, palladium, or platinum
with an anthraquinone, reaction of barium peroxide
with sulfuric acid and by oxidation of isopropanol
with acetone are also industrial processes for the
production of hydrogen peroxide. Hydrogen peroxides
are marketed in concentration of 3-90% by wt as
a solution in water. 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, e.g. organic peroxides,
perhydrates. It is also used in water and sewage
treatment, mining, electronics, food and cosmetic
indutry.
