Brief Overview

 

Hydrogen peroxide is colorless, dense, sharp odor, slippery and unstable liquid .Hydrogen peroxide is corrosive and a strong oxidizer and has a formula of H2O2.It deteriorate with time to avoid deterioration we have to add chemicals like acetanilide. When decompose it gives water and oxygen. It gives spontaneous combustion when coming in contact with organic material. Its contact may irritate the eyes, skin, and mucous membrane. It can be found in organisms and as a by-product of oxidative metabolism. Due to differences in effects of hydrogen bonding, an aqueous solution of hydrogen peroxide and pure solutions differs in freezing point temperature. In aqueous solution, water and hydrogen peroxide forms a eutectic mixture and exhibits a freezing point depression.

 

 

Manufacturing Process

 

Anthraquinone process for manufacturing of hydrogen peroxide which includes 4 main steps:

1. Hydrogenation of an anthroquinone: - A solution of the 2-ethylanthraquinone in a mixed solvent system containing a non-polar hydrocarbon and a polar solvent, and a suspension of a nickel or palladium-based catalyst on a solid support, is hydrogenated using hydrogen gas at 320 K.  Reduction to the 2- alkylanthraquinol occurs.  The catalyst is removed by filtration and recycled.

2. Oxidation of the anthraquinol:-The solution of 2-ethylanthraquinol is then oxidized by air to a hydroperoxide, which reacts with water to reform 2-ethylanthraquinone and produce a dilute solution of hydrogen peroxide. Thus the overall reaction is:

                                H2 + O2 ------>H2O2

3. Extraction of hydrogen peroxide solution:-Water is added to extract the peroxide as an aqueous solution containing 40% hydrogen peroxide.  The organic solvent layer is recycled to the hydrogenation unit for further reaction.

4. Purification and concentration of hydrogen peroxide:-The aqueous hydrogen peroxide solution is treated with organic solvents and by air being pumped through to remove residual quinone and solvents and produce the standard 40% product.  



Textile Industry


Hydrogen peroxide is used as a bleaching agent in the textile industry and they are more environmental friendly than the chlorine-based bleaches. Hydrogen peroxide is also used in dyes. Sulfur dyes work with an oxidation-reduction dyeing method and hydrogen peroxide is used as an oxidizing agent. Once the dyes are adsorbed onto the cellulosic, oxidation will settle the dyes permanently and changing it into a water-insoluble form.
