Hydrogen peroxide

Hydrogen peroxide H2O2 with the chemical formula was invented by Louis Jacques Thenard in 1818 (Wikipedia.com). This compound is an inorganic chemical that has strong oxidizing properties. Raw material for making hydrogen peroxide is hydrogen gas (H2) and oxygen gas (O2). Technology is widely used in the auto industry is the hydrogen peroxide oxidation of anthraquinone.

H2O2 is colorless, odorless typical slightly acidic, and dissolves well in water. Under normal conditions (ambient conditions), hydrogen peroxide is very stable with a decomposition rate of roughly less than 1% per year.

The majority of the use of hydrogen peroxide is to utilize and manipulate the decomposition reaction, which in essence produces oxygen. At this stage of the production of hydrogen peroxide, chemical stabilizer material is usually added in order to inhibit the rate of decomposition. Including the decomposition that occurs during the hydrogen peroxide product in storage. In addition to generating oxygen, hydrogen peroxide decomposition reaction also produces water (H2O) and heat. Exothermic decomposition reaction that occurs is as follows:

H2O2 -> H2O + 23: 45 + 1/2O2 kcal / mol

Factors affecting hydrogen peroxide decomposition reaction is:

1. Certain organic materials, such as alcohol and gasoline
2. Catalysts, such as Pd, Fe, Cu, Ni, Cr, Pb, Mn
3. Temperature, the reaction rate of decomposition of hydrogen peroxide increased by 2. 2 x every increase of 10 ° C (in the temperature range 20-100oC)
4. Uneven surface of the container (active surface)
5. Suspended solids, such as dust particles or other impurities
6. The higher the pH (more alkaline) the higher the rate of decomposition
7. Radiation, particularly radiation of light with short wavelengths

Hydrogen peroxide can be used as a bleach or bleaching agents agent in the pulp, paper and textiles. These compounds are also commonly used in wastewater treatment processes, chemical industry, the manufacture of detergents, food and beverage, medical, and industrial electronics (PCB manufacture).

One of the benefits of hydrogen peroxide compared with other oxidizing agents is its environmentally friendly because it leaves no harmful residue. Oksidatornya strength can also be set according to need. For example in the pulp and paper industry, the use of hydrogen peroxide is usually combined with NaOH or caustic soda. The more alkaline, then the hydrogen peroxide decomposition rates even higher. Hydrogen peroxide needs of the industry will continue to increase from year to year.
