Xylene (from Greek ξύλο, xylo, "wood"), xylol or dimethylbenzene is any one of three isomers of dimethylbenzene, or a combination thereof. With the formula (CH3)2C6H4, each of the three compounds has a central benzene ring with two methyl groups attached at substituents. They are all colourless, flammable liquids, some of which are of great industrial value. The mixture is referred to as both xylene and, more precisely, xylenes.

NB: IN Greek, the letter "Chi" pronounced as in the Scottish LOCH, is written as Χ, χ.
Hence, Χημεία (Cheeméa) = Chemistry.
However, the letter "Xi" pronounced as the "x" in FOX even at the beginning of words, is written as Ξ, ξ.
Hence, Ξυλένιο (Xeelénio) = Xylene!
X is such a problematic letter in English!
