Hydrogen Peroxit

Physical properties:

Hydrogen peroxide (hydrogen peroxide) has the chemical formula H2O2, which is a transparent liquid, slightly more viscous than water. H2O2 has strong oxidizing properties and is therefore a strong bleaching agent used as a disinfectant, as well as an oxidizing agent, and (especially at high concentrations such as HTP). Hydrogen peroxide is a propellant in rockets. And hydrogen peroxide is a weak acid in aqueous solution

Chemical properties:

Hydrogen peroxide can break down naturally into water and oxygen. Usually it reacts as an oxidizing agent, but there are many reactions in which it reacts as a reducing agent, releasing oxygen as a by-product. It also very quickly generates inorganic and organic peroxides.

In Industry

About 60% of the world's hydrogen peroxide production is used to bleach pulp and paper. The second largest industrial application is the production of sodium percarbonate and sodium perborate which is used as a mild detergent in laundry detergents.

It is also used in the production of certain organic peroxide compounds such as dibenzoyl peroxide, which is used as a free radical primer in polymerization and other chemical reactions. It is also used to produce epoxides such as propylene oxide. Reacts with carboxylic acids to produce the corresponding “per- acids”; for example peracetic acid of industrial use is prepared in this way from acetic acid. Similarly, meta-chloroperoxybenzoic acid (MCPBA), which is widely used in laboratories, is also prepared from meta-chlorobenzoic acid.

Hydrogen peroxide is used in some wastewater treatment processes to remove organic impurities. This is achieved by advanced oxidation, such as the Fenton reaction, which uses it to generate highly reactive hydroxyl radicals (-OH). It can destroy stubborn organic contaminants such as aromatic compounds or halogens. It can also oxidize sulfur compounds present in waste products, an application commonly used to reduce odors.

In medical

Hydrogen peroxide has been used as a disinfectant and disinfectant for many years. While its use has declined in recent years due to the popularity of OTC products that are more pleasant-tasting and more readily available, it is still used by many hospitals, doctors, and dentists. sterilizing, cleaning and handling everything from floors to root canal surgeries.

The 35% hydrogen peroxide is known as “hydrogen peroxide”, with medicinal or therapeutic values ​​considered to be hydrogen peroxide therapy. Advocates of this product claim that it can be diluted and used in “super-oxidation therapy” to treat AIDS, cancer and many other diseases; Some also complain that information about the beneficial uses of peroxides is banned by the scientific community.

More recently, other medical practitioners have also used extremely low doses of intravenous hydrogen peroxide (less than 1%) in hydrogen peroxide therapy – a controversial medical treatment for cancer. letters. However, according to the American Cancer Society, "there is no scientific evidence that hydrogen peroxide is safe, effective, or useful in the treatment of cancer." They also recommend that cancer patients “maintain the care of specialists who use tried and tested treatments and approved treatment trials of these treatments.” promising new value”.
