China, the United States, and South Korea are the leading exporters of o-Xylene, collectively accounting for over 45% of global exports in 2023–2024, while India, Vietnam, and Mexico represent the fastest-growing import markets. Major importers include Taiwan, Thailand, and Germany—key regional hubs for downstream petrochemical manufacturing. Import volumes into Southeast Asia have risen steadily since 2022, coinciding with moderate upward pressure on o-Xylene prices amid tightening supply from Northeast Asian producers.
o-Xylene is a clear, colorless, volatile liquid with a characteristic aromatic odor. It is an aromatic hydrocarbon and one of the three isomeric dimethylbenzenes, with a melting point of −25 °C and a boiling point of 144 °C. Primarily used as a chemical intermediate, it serves as a key feedstock in the production of phthalic anhydride via catalytic oxidation. This derivative is essential for manufacturing orthophthalate plasticizers, unsaturated polyester resins, and alkyd resins. Its principal application areas include plastics, coatings, adhesives, and construction materials.
(1) It is mainly used in the production of phthalic anhydride(2) O-xylene is the raw material for the production of germicide fenramine, tetrachlorophenyl peptide and the herbicide bensulfuron-methyl. It is used as intermediate for the manufacture of o-methyl benzoic acid.(3) It is mainly used as chemical raw materials and solvents. It can be used to produce phthalic anhydride, dyes, pesticides and drugs, such as vitamins. It can also be used as aviation gasoline additives.(4) Used as chromatographic standards and solvents(5) As raw materials of synthesis of anhydride and other organic synthesis;
It appears as colorless transparent liquid with aromatic odor. It is miscible with ethanol, ethyl ether, acetone and benzene but insoluble in water.
This chemical is included in Basic Chemicals - Aromatics. See more about what is o-Xylene and o-Xylene SDS information.
