Product name: hydrogen peroxide. Alias hydrogen dioxide, hydrogen peroxide, ethoxane
English name: hydrogen peroxide
Molecular formula: H2O2
Relative molecular mass: 34.01
Hydrogen peroxide, the chemical formula H2O2. Pure hydrogen peroxide is a light blue viscous liquid that can be miscible with water in any proportion. It is a strong oxidant. Its aqueous solution is commonly known as hydrogen peroxide and is a colorless and transparent liquid. Its aqueous solution is suitable for medical wound disinfection, environmental disinfection and food disinfection. Under normal circumstances, it will slowly decompose into water and oxygen, but the decomposition rate is extremely slow. The way to speed up the reaction is to add a catalyst-manganese dioxide, etc. or irradiate it with shortwave rays.
There are oxidation and reduction effects in different aminoguanidine hydrochloride uses situations. Used in photographic stain remover; blue thinning of color positive film; super-proportional thinning of film, etc. Easily decompose, not easy to keep for a long time.
The uses of hydrogen peroxide are divided into three categories: medical, primary and industrial. The daily disinfection is medical hydrogen peroxide, which can kill intestinal pathogenic bacteria, pyogenic cocci, and pathogenic yeasts. It is generally used for surface disinfection. The p hydroxybenzaldehyde structure has an oxidizing effect.
However, if the concentration of medical hydrogen peroxide is equal to or lower than 3%, if it is wiped on the wound surface, there will be a burning sensation, the surface will be oxidized to white and bubbling, just wash it with water, and the original skin color will be restored after 3-5 minutes.
In the chemical industry, it is used as raw material for the production of sodium perborate, per-material materials, peroxyacetic acid, sodium chlorite, thiourea peroxide, etc., as well as oxidizing agents for tartaric acid and vitamins. In the pharmaceutical industry, it is used as a fungicide, disinfectant, and an oxidant for the production of thiram insecticide and 40l balanced colony agent. In the printing and dyeing industry, it is used as a bleaching agent for cotton fabrics to reduce the color after dyeing with dyes. Used to remove iron and other heavy metals in the production of metal salts or other compounds. It is also used in electroplating solution to remove inorganic impurities and improve the quality of plated parts. It is also used for bleaching wool, raw silk, ivory, pulp, fat, etc. High-concentration hydrogen peroxide can be used as a combustion-supporting agent for fire building power.
Civil use: To deal with the peculiar smell of the kitchen sewer, wholesale tear gas of hydrogen peroxide, add water and washing powder in the pharmacy, and pour it into the sewer to decontaminate, disinfect and sterilize.
