The industrial production of hydrogen peroxide (H2O2) is a cornerstone of many chemical processes, from bleaching and disinfection to chemical synthesis. Among the various methods employed, the anthraquinone process stands out as the dominant technology. Central to this process is the intermediate compound 2-Ethyl Anthraquinone (2-EAQ), identified by its CAS number 84-51-5. Understanding the properties and sourcing of this compound is crucial for manufacturers of hydrogen peroxide.

The Anthraquinone Process: A Closer Look

The anthraquinone process involves a cyclic chemical reaction where an alkylanthraquinone, such as 2-EAQ, is hydrogenated to form the corresponding alkylanthrahydroquinone. This reduced form is then oxidized with air or oxygen, regenerating the original alkylanthraquinone and producing hydrogen peroxide. The cycle is completed by extracting the H2O2 with water. The efficiency and economics of this entire cycle are heavily dependent on the performance and stability of the alkylanthraquinone used. This is where 2-Ethyl Anthraquinone, with its specific chemical structure and properties, proves invaluable.

Why 2-Ethyl Anthraquinone is Preferred

2-Ethyl Anthraquinone is favored in the H2O2 manufacturing process due to its excellent chemical stability, high solubility in the working solution, and efficient regeneration during the oxidation step. Its pale yellow flake or powder appearance belies its critical function. Sourcing 2-EAQ with a minimum purity of 99% is paramount. Impurities can hinder the hydrogenation or oxidation reactions, reduce the overall yield of H2O2, and potentially contaminate the final product. Therefore, when seeking to buy 2-ethyl anthraquinone for this application, prioritizing a reputable hydrogen peroxide intermediate manufacturer is essential.

Sourcing 2-EAQ: Key Considerations for Buyers

For companies looking to secure a reliable supply of 2-EAQ, several factors come into play:

  • Manufacturer Reputation: Opt for suppliers who are established manufacturers, like NINGBO INNO PHARMCHEM CO.,LTD., rather than intermediaries. This ensures better control over quality and pricing.
  • Quality Assurance: Always verify that the supplier can provide Certificates of Analysis (COA) detailing the purity (≥99%), melting point (107-111°C), and impurity levels (e.g., benzene insoluble matter ≤0.05%).
  • Price and Volume: Inquire about the CAS 84-51-5 price and explore options for bulk purchasing to achieve cost efficiencies. Manufacturers in China often offer competitive pricing due to economies of scale.
  • Logistics and Packaging: Ensure the supplier offers suitable packaging (e.g., 25kg or 500kg bags) and reliable logistics to deliver the material safely and on time.

The effective synthesis of hydrogen peroxide hinges on the quality and consistent availability of its key intermediates. 2-Ethyl Anthraquinone, with its specific chemical characteristics and essential role in the anthraquinone process, is a critical component. By partnering with a trusted dye intermediate supplier who also excels as a hydrogen peroxide intermediate manufacturer, businesses can ensure operational continuity and product excellence. When planning your next procurement, remember to purchase 2-ethyl anthraquinone from a supplier committed to purity and reliability.
