Xylene - Wikipedia
In organic chemistry, xylene or xylol (from Greek ξύλον (xylon) 'wood'; [1] [2] IUPAC name: dimethylbenzene) are any of three organic compounds with the formula (CH 3) 2 C 6 H 4. 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 ...

Xylene is a major industrial chemical derived mainly from petroleum refining. It occurs in three isomeric forms (ortho, meta and para) and is produced and used both as ‘mixed xylenes’ (usually containing 10–15% ethylbenzene) and as the individual isomers. Xylene is used as a solvent in paints, inks, adhesives and insecticides.
