Xylenes

Xylenes are a group of aromatic hydrocarbons with the chemical formula C₈H₁₀. They are colorless liquids with a sweet odor and are found naturally in petroleum and coal tar. Xylene exists in three isomeric forms:

Xylene is also used in the production of terephthalic acid, a precursor to polyester fiber.

Exposure to xylene can occur through inhalation, ingestion, or skin contact. Inhalation is the most likely route of exposure for most people. Short-term exposure to high levels of xylene can cause dizziness, headache, nausea, vomiting, and irritation of the nose and throat. Long-term exposure to xylene can damage the nervous system, kidneys, and liver.

In organic chemistry, xylene or xylol are any of three organic compounds with the formula (CH₃)₂C₆H₄. They are derived from the substitution of two hydrogen atoms with methyl groups in a benzene ring; which hydrogens are substituted determines which of three structural isomers results.
