Application

Anthraquinone serves primarily as a catalyst in the paper industry to enhance pulp production yield and strengthen fibers by facilitating the reduction of cellulose to carboxylic acid. Additionally, its role as a precursor is crucial in the formation of a wide range of dyestuffs, such as alizarin. This versatile compound demonstrates notable solubility in ethanol, ether, and acetone and is characterized by its light yellow to green crystalline form. With unique chemical properties that include a melting point of 286℃, anthraquinone is influential both in industrial applications and dye production. While its utility in various fields is pronounced, it also has specific safety considerations, given its slightly combustible nature and very slight solubility in water.
