2,3-Dimethylnaphthalene is an important aromatic hydrocarbon intermediate. It is widely used for synthesizing high-performance polyester resins, heat-resistant coatings and engineering plastics. It serves as core raw material to produce dye intermediates and fluorescent materials with stable color property. Applied in petrochemical refining and organic synthesis to prepare various naphthalene derivatives. It can also be used as lubricant additive and heat conduction medium, possessing broad application prospect in fine chemical, new material and chemical synthesis industries.
