Mixed xylene is a mixture of three isomers of xylene: ortho-xylene, meta-xylene, and para-xylene. It is a colorless, flammable liquid with a sweet odor and is commonly used as a solvent in various industrial applications, including the production of plastics, synthetic fibers, and coatings. Para-xylene, one of its components, is particularly valuable in the manufacture of polyester fibers and plastics, making mixed xylene an essential raw material in the petrochemical industry.
