2 Applications
Sodium carbonate can be used for the production of H2O2, hydrogen peroxide (H2O2) Common name of hydrogen peroxide ,
The following is a colorless liquid at room temperature , it is difficult to ionize decomposition. As a classical chemical products, industrial than 100 years ago began production . With the growth of social needs , particularly the need for ecological and environmental protection , hydrogen peroxide recent years by people of all ages , and is known as the ” green oxidant .” In order to store , transport, easy to use, industrial use alcohol to precipitate a solid which was converted to the sodium percarbonate crystals ( chemical formula : 2Na2CO3 · 3H2O2), the crystal has the duality of Na2CO3 and H2O2 . Generating an alcohol precipitation process is as follows : when 0 ~ 5 ℃, to a saturated solution of Na2CO3 , and a stabilizer added first H2O2 (MgCl2 and Na2SiO3), the reaction sufficiently , and then isopropanol was added , filtered liquid separation , i.e., too carbonate crystals. After treatment available oxygen capsules , tablets that solid oxygen , oxygen in ponds for stereo , water purification . Multifunctional detergent , ie washing decontamination , while both bleaching, sterilization , disinfection and other effects, has become the development trend of detergent , plus there are a lot of foreign detergent component bleaching effect , the country will also gradually to develop in this area . Since percarbonate tasteless , non-toxic, easy to dissolve in cold water , strong detergency, when dissolved in water can release oxygen bleach sterilization and play a variety of effects, in line with the development trend of modern detergents . More than traditional powdered detergent used sodium borate , sodium borate, but the presence of dissolved slow, expensive and boron impact on crops and other shortcomings . And sodium carbonate , sodium perborate lower than the cost , good solubility , suitable for use in cold areas and winter , crops will not cause harm , and therefore the production of sodium carbonate in detergent applications increasing, at present, has been widely percarbonate used for household and industrial washing , bleaching , bactericides, for synthetic fibers, animal fibers , synthetic resin fibers , pulp production areas such as fat , good bleaching effect , no damage to the fabric , non-yellowing .
3 reaction equation
2Na2CO3 · 3H2O2 = 2Na2CO3 +3 H2O2
Na2CO4 + H2O = Na2CO3 + H2O2
2H2O2 = 2H2O + O2 ↑
After water was added sodium carbonate peroxide , rapidly produce hydrogen peroxide, hydrogen peroxide is unstable , produce oxygen and water. The final reaction of sodium carbonate , dry white powder or as granules, odorless , is an alkaline salt thereof. Commonly known as soda , eating the human body without harm, does not produce lead, arsenic and other heavy metals.
