General
- Hydrogen
peroxide (H2O2) is a very pale blue liquid which appears colorless
in a dilute solution, slightly more viscous than water.
- Hydrogen
peroxide is a weak acid. It has strong oxidizing properties and is
therefore a powerful bleaching agent that is mostly used for
bleaching paper.
- Hydrogen
Peroxide found its use as a disinfectant, as an oxidizer, as an
antiseptic, and in rocketry as a monopropellant, and in
bipropellant systems.
- The
oxidizing capacity of hydrogen peroxide is so strong that the
chemical is considered a highly reactive oxygen species.
Process
- Hydrogen
peroxide is naturally produced as a byproduct of oxygen
metabolism, and virtually all organisms possess enzymes known as
peroxidases.
- Hydrogen
peroxide always decomposes exothermically into water and oxygen
gas spontaneously.
- Hydrogen
peroxide is a weak acid, and it can form hydroperoxide or
peroxide salts or derivatives of many metals.
- Hydrogen
peroxide is manufactured by the autoxidation of
2-ethyl-9,10-dihydroxyanthracene to 2-ethylanthraquinone and
hydrogen peroxide using oxygen from the air. This is known as
the Riedl-Pfleiderer process.
Applications
- H2O2 can
be used either as a monopropellant or as the oxidizer
component of a bipropellant rocket.
-
Industrial applications for hydrogen peroxide include the
manufacture of sodium percarbonate and sodium perborate, used
as mild bleaches in laundry detergents.
- Hydrogen
peroxide can be used as a toothpaste when mixed with correct
quantities of baking soda and salt.
- Hydrogen
peroxide and benzoyl peroxide are sometimes used to treat
acne.
- Hydrogen
peroxide is used as an emetic in veterinary practice.
Report
-
Antioxidant potential of silk protein sericin against
hydrogen peroxide-induced oxidative stress in skin
fibroblasts.
-
Hydrogen Peroxide Health Risks concerning Teeth Whitening.
- The
Food and Drug Administration (FDA) has not approved hydrogen
peroxide for human consumption; therefore, the sale of
hydrogen peroxide for this purpose is illegal.
- Study
of wet hydrogen peroxide oxidation process applied for
advanced treatment of wastewaters containing high phenol
concentrations.
