How To Make Hydrogen Peroxide
The method of making hydrogen peroxide
To make hydrogen peroxide, you need to understand the reason. For hydrogen peroxide, the chemical name is hydrogen peroxide, and the molecular formula is $H_2O_2 $.
One method is to use barium peroxide $ (BaO_2) $to react with dilute sulfuric acid $ (H_2SO_4) $. Take an appropriate amount of barium peroxide, put it in a clean container, and slowly inject dilute sulfuric acid. The reaction formula is: $BaO_2 + H_2SO_4 = BaSO_4? + H_2O_2 $. Barium sulfate $ (BaSO_4) $is a precipitate, which can be filtered and removed, and the remaining solution contains hydrogen peroxide.
There is an electrolysis method. An aqueous solution of ammonium bisulfate $ (NH_4HSO_4) $is used as an electrolyte, and an electric current is passed in a specific electrolysis device. The reaction occurs at the anode: $2HSO_4 ^ - - 2e ^ - = S_2O_8 ^ {2 - } + 2 H ^ + $, the resulting persulfate $ (S_2O_8 ^ {2 -}) $is hydrolyzed in water: $S_2O_8 ^ {2 - } + 2H_2O = 2HSO_4 ^ - + H_2O_2 $. After subsequent treatment, pure hydrogen peroxide can be obtained.
Furthermore, prepared by anthraquinone method. Dissolve alkyl anthraquinone (such as 2-ethyl anthraquinone) in an organic solvent (such as a mixture of heavy aromatics and trioctyl phosphate) to form a working solution. The working liquid is reacted with hydrogen in the presence of a catalyst (such as a palladium catalyst), and alkyl anthraquinone is hydrogenated to alkyl anthraquinone. After that, in contact with air or oxygen, alkyl anthraquinone is re-oxidized to alkyl anthraquinone, and hydrogen peroxide is generated at the same time. The process can be repeated, and hydrogen peroxide can be separated through extraction, purification and other steps.
To make hydrogen peroxide, you need to abide by the procedures and pay attention to safety.
