Anthraquinone (CAS 84-65-1) is a cornerstone organic chemical with a rich history and diverse applications across multiple industries. Its unique molecular structure and chemical properties make it an invaluable intermediate, particularly in the paper and textile sectors. As NINGBO INNO PHARMCHEM CO.,LTD., a prominent chemical manufacturer and supplier from China, we are committed to providing detailed insights into the compounds we offer, empowering our clients with knowledge for optimal utilization.

Chemically, Anthraquinone is an aromatic organic compound with the molecular formula C14H8O2. It is a derivative of anthracene, featuring two carbonyl groups on the central ring. This structure imbues Anthraquinone with specific reactivity that is leveraged in various industrial processes. Its physical appearance is typically a yellow or light grey to grayish green powder, and it possesses a relatively high melting point, generally above 280°C, indicating its thermal stability.

One of the most significant industrial applications of Anthraquinone is its role as a catalyst in the paper industry. During the pulping process, it is added to alkaline solutions to accelerate the digestion of wood chips. This catalytic action helps in the efficient removal of lignin from cellulose fibers, leading to an increase in pulp yield and improved fiber quality. The enhanced strength and integrity of the fibers contribute to the overall quality of the final paper products.

Furthermore, Anthraquinone is a fundamental precursor in the synthesis of a wide spectrum of dyes, known collectively as anthraquinone dyes. These dyes are highly prized for their exceptional colorfastness, including resistance to light, washing, and chemical agents. The versatility of Anthraquinone allows for the creation of dyes in virtually every color, from vibrant reds and blues to subtle greens and yellows, making it indispensable for textile dyeing, printing inks, and specialized coatings.

The solubility characteristics of Anthraquinone are also noteworthy. While it exhibits very low solubility in water, it is more soluble in certain organic solvents like acetone, ether, and hot alcohol, and notably in concentrated sulfuric acid, where it forms characteristic colored solutions. Understanding these properties is key for formulators when designing reaction conditions or solvent systems.
