2-Ethylanthraquinone (2-EAQ) is an organic compound that plays a pivotal role in various industrial chemical processes, most notably as the primary raw material in the production of hydrogen peroxide via the anthraquinone auto-oxidation method. Its chemical structure, derived from anthraquinone with an ethyl group attached at the 2-position, imparts specific properties that make it exceptionally well-suited for this critical application. Understanding the chemical foundation of 2-EAQ is key to appreciating its industrial significance.

Chemically, 2-EAQ is a stable compound, typically appearing as light yellow flakes. Its molecular formula is C16H12O2, and it has a molecular weight of 236 g/mol. A key characteristic relevant to its industrial use is its melting point, which typically falls between 109-112°C. This allows it to be processed and handled within a manageable temperature range. The purity of 2-EAQ is paramount for efficient operation in the hydrogen peroxide synthesis cycle. Impurities, such as those indicated by low levels of metals (Fe, S, Cl) and benzene insolubles, can negatively affect catalyst performance and product yield. Manufacturers like NINGBO INNO PHARMCHEM CO.,LTD. focus on producing high-assay 2-EAQ (≥99%) with minimal impurities to ensure optimal results for their clients.

The core function of 2-EAQ in hydrogen peroxide production lies in its ability to readily undergo hydrogenation to form 2-ethylanthrahydroquinone (EAHQ). EAHQ is then oxidized by air, regenerating the 2-EAQ and forming H2O2. This cyclic process is efficient because the 2-EAQ is recycled, and the hydrogen peroxide is formed directly in the reaction mixture, allowing for easy extraction. The stability of the 2-EAQ molecule under the process conditions is crucial for the longevity of the catalytic system and the overall economics of H2O2 production. The benefits of 2-EAQ in H2O2 synthesis are thus deeply rooted in its chemical stability and reactivity profile.

As a significant industrial chemical intermediate, 2-EAQ is manufactured in large quantities. Its production capacity and quality control are therefore critical factors for the industries that rely on it. NINGBO INNO PHARMCHEM CO.,LTD., a reputable supplier in China, ensures that its 2-ethylanthraquinone meets rigorous technical specifications, including assay, moisture content, and impurity levels.
