Any of three isomers of dimethylbenzene (ortho, meta, and para-xylene), with molecular formula C₈H₁₀ or (CH₃)₂C₆H₄. Xylenes are aromatic hydrocarbons used as industrial solvents and chemical intermediates. Para-xylene is used to produce terephthalic acid for PET plastic.
Para-xylene is oxidised to produce terephthalic acid used to make polyethylene terephthalate (PET) plastic and polyester fibres. Xylene is used as a solvent in paints, lacquers, adhesives, and in histology laboratories. It is a starting material for dyes and pharmaceuticals.
Xylene is flammable and its vapours are toxic, causing central nervous system depression, headache, and dizziness. Prolonged exposure can affect the liver and kidneys. It requires proper ventilation, respiratory protection, and is a listed hazardous substance.
