2-Ethylanthraquinone, identified by its CAS number 84-51-5, is a significant organic compound primarily known for its role as a key intermediate in the production of hydrogen peroxide (H₂O₂). As a pale yellow solid, its chemical structure and properties are optimized for use in the well-established anthraquinone process, a cornerstone of global H₂O₂ manufacturing. Understanding these properties is crucial for chemical manufacturers seeking to buy 2-ethylanthraquinone for their operations.

The typical appearance of 2-ethylanthraquinone is a light yellow powder, with a specified assay of 99% minimum purity. This high purity is essential, as it directly impacts the efficiency and yield of the hydrogen peroxide synthesis. Its physical characteristics, such as a melting point typically between 107.0 – 109.0℃, are important for handling and processing. Furthermore, parameters like low insoluble matter in benzene (≤ 0.5%) and minimal moisture content (≤ 0.2%) indicate its suitability for sensitive chemical reactions. These specifications are often provided by suppliers to assure customers of product quality.

The primary application of 2-ethylanthraquinone is its use as a raw material in the hydrogen peroxide production process. In this cyclic autoxidation method, 2-EAQ is hydrogenated to 2-ethylanthrahydroquinone, which is then oxidized by air to produce hydrogen peroxide. The 2-ethylanthraquinone is regenerated, making the process economically viable. The selectivity of 2-ethylanthraquinone in this pathway is remarkably high, minimizing side reactions and ensuring a cleaner production of H₂O₂.

Beyond its primary role, 2-ethylanthraquinone may find applications in research and development for new chemical syntheses or process improvements. The ability to purchase 2-ethylanthraquinone in bulk quantities, often packed in 25kg bags, signifies its industrial scale usage. Proper storage is also emphasized; keeping the compound in a cool, dry place, protected from direct sunlight, helps maintain its stability and efficacy. NINGBO INNO PHARMCHEM CO., LTD. provides this essential chemical, ensuring that industries have access to a reliable source for their manufacturing needs. The price and availability of 2-ethylanthraquinone are key considerations for companies involved in hydrogen peroxide manufacturing.

In conclusion, 2-Ethylanthraquinone (CAS 84-51-5) is a fundamental chemical intermediate, critical for the efficient and large-scale production of hydrogen peroxide. Its well-defined properties, high purity, and the established efficacy of the anthraquinone process make it an indispensable compound for the chemical industry. Sourcing this material from experienced manufacturers and suppliers like NINGBO INNO PHARMCHEM CO., LTD. is key to operational success.
