Description

General description

p-Xylene is an aromatic liquid , which is an isomeric form of xylene. It can be produced via Diels-Alder reaction between 2,5-dimethylfuran and ethylene catalyzed by zeolite.

p-Xylene is an aromatic liquid, which is an isomeric form of xylene. It can be produced via Diels-Alder reaction between 2,5-dimethylfuran and ethylene catalyzed by zeolite.

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.

Application

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