Commercial Production of Hydrogen Peroxide
On the commercial production of hydrogen peroxide
Hydrogen peroxide has a wide range of uses in today's commercial field. Its commercial production method is the most important in the industry.
The anthraquinone method is the first. This is the most commonly used method for the preparation of hydrogen peroxide. Using anthraquinone derivatives as the medium, in an organic solvent, hydrogen and oxygen react with the force of a catalyst to undergo a series of reactions. Initially, anthraquinone reacts with hydrogen under the action of a catalyst to produce hydroanthraquinone. This step is the hydrogenation process. The resulting anthraquinone reacts with oxygen and is converted back into anthraquinone, and hydrogen peroxide is produced at the same time. This is an oxidation process. After this cycle, anthraquinone can be used repeatedly to continuously produce hydrogen peroxide. In this process, the choice of organic solvent is crucial, which needs to have good solubility to anthraquinone and hydroanthraquinone, and its chemical properties are stable, which is convenient for subsequent separation and recovery. The activity and selectivity of the catalyst also have a great impact on the reaction efficiency and the purity of hydrogen peroxide.
Furthermore, electrolysis has also been used for commercial production of hydrogen peroxide. By electrolyzing an aqueous solution of bisulfate, at the anode, the hydrogen sulfate ion loses electrons and generates persulfate ion. This persulfate ion undergoes hydrolysis in water to generate hydrogen peroxide. However, electrolysis method has high energy consumption, strict requirements on electrode materials, and complex equipment, so it is gradually replaced by anthraquinone method. However, in some specific scenarios, such as where the purity of hydrogen peroxide is extremely high and the cost of electricity is low, electrolysis still has its application value.
Another isopropanol oxidation method. In the presence of a catalyst, isopropanol reacts with oxygen to form acetone and hydrogen peroxide. The advantage of this reaction is that the raw material isopropanol is widely sourced and relatively low cost. However, the separation and recovery of the product acetone needs to be properly handled, and the reaction conditions are strictly controlled during the reaction process to ensure the yield and purity of hydrogen peroxide.
In summary, all methods for commercial production of hydrogen peroxide have their own advantages and disadvantages. The anthraquinone method has become the mainstream production method today due to its high efficiency, economy and relatively simple operation. However, each method still has unique value under specific needs and conditions, providing a variety of options for the commercial production of hydrogen peroxide.
