    General description

    p-Xylene is an aromatic liquid [1], which is an isomeric form of xylene.[2] It can be produced via Diels-Alder reaction between 2,5-dimethylfuran and ethylene catalyzed by zeolite.[3]
    p-Xylene is an aromatic liquid[4], which is an isomeric form of xylene.[5] It can be produced via Diels-Alder reaction between 2,5-dimethylfuran and ethylene catalyzed by zeolite.[6]
    p-Xylene is an environmental pollutant belonging to the class of volatile organic compounds. It is emitted from a variety of sources including adhesives, degreasing agents, combustion products of wood and fuels, industrial paints, aerosols, etc.[7]

    Application

    p-Xylene may be used as an analytical reference standard for the quantification of the analyte in occupational environmental samples[8] and aqueous samples[9][10] using gas chromatography technique with different modes of detection.
