Product Description Hydrogen peroxide (chemical symbol H2O2 - it's basically water with an extra oxygen atom!) is a weakly acidic, colourless liquid which can easily be mixed with water. It can also be pale blue in its pure form, although as it is an unstable compound and decomposes when exposed to heat, it is usually kept in a slightly acidic solution in the presence of a stabilizer.Physical Properties:Pure H2O2 is a colorless odorless thick and transparent fluid. In large amounts, its color appears to be light blue.Its boiling point is 151 °C and the freezing point is -0.89 °C. It rapidly decomposes at its boiling point. Hence its distillation is done at low pressure. Its boiling point is 68 °C at 26mm pressure.Its relative density is 1.4694 at 0 °C and its relative density at 25 °C is 1.64.It is soluble in water, ether and alcohol.This puts blisters on the skin.Key Features: Safety: normal temperature, normal pressure, non-toxic, no residue;Fast: Rapid sterilization cycle and cost savingsEffective: Hydrogen peroxide gas has excellent material compatibility (devices, electronic components and building materials) and is easier to verifyExtensive: It has a broad-spectrum bactericidal effect, suitable for the disinfection of fungi, bacteria, viruses and spores.How Is Hydrogen Peroxide Produced?The Step-by-Step Process Of Making Hydrogen PeroxideTo put it in more complex terms, hydrogen peroxide is generally made according to this four-step process:Hydrogenation on a palladium catalyst creates a reaction between hydrogen and anthraquinone which produces anthrahydroquinone.The palladium catalyst is filtered out of the solution.Oxidation takes place by blowing air through the solution, forming hydrogen peroxide.The hydrogen peroxide is extracted, purified, and then concentrated by vacuum distillation.Hydrogen peroxide also occurs naturally in surface and groundwater, as well as in the atmosphere. It is also made in humans and animals as a part of biochemical processes.Auto-Oxidation MethodThis is the modern method of making Hydrogen peroxide in large quantities. In this, 2-Ethyl-anthraquinone is dissolved in an organic solvent and it is reduced to hydrogen in the presence of Pd. The 2-Ethyl-anthraquinone derived from this action changes again to 2-Ethyl-anthraquinone. And H2O2 is obtained.The industrial manufacture of H2O2 can be achieved by steam distillation at a low pressure of Perdisulphuric Acid. About 30% solution of H2O2 is obtained by this method.Over 99% of the world's hydrogen peroxide is manufactured by an autoxidation process. While the overall equation for this process is fairly simple (H2 + O2 -> H2O2), there is obviously a lot more to it than that!Fixed Bed Process Hydrogen PeroxideThere are several methods for hydrogen peroxide production and manufacturing, among them the AO(auto-oxidation) process is the most prevailing one. In this process, 2-alkyl anthraquinone is mixed with organic solvent to make up the working solution, which is hydrogenated in presence of catalyst, and the resulting is oxidized by air (or oxygen) in counter-current way before being extracted, regenerated, purified and enriched to get commercial hydrogen peroxideproduct. Depending upon the different reactor type in the hydrogenation unit, AO process is further divided into Fixed Bed Reactor Process and Fluidized Bed Reactor Process. WellCare is a leading supplier of technology and turnkey solutions and services for hydrogen peroxide manufacturing and hydrogen peroxide production plants. WellCare provides both fixed bed reactor process and fluidized bed reactor process. The fixed bed reactor process SL TEC provides is the most advanced technology in China. It employs heavy aromatics-TBU-TOP tertiary solvent in the working solution and alumina-supported Pd catalyst with high activity.Process Flow:Reference Plant:Factory Workshop Presents:
