The meaning of XYLYLENE is any of several isomeric bivalent radicals C8H8 derived from the three xylenes by removal of one hydrogen atom from each of two carbon atoms; especially : any of the three radicals having the formula —CH2C6H4CH2—; phenylene-di-methylene.

The chemical compound xylylene dichloride (C 6 H 4 (CH 2 Cl) 2) is a white to light yellow sandlike solid. [1] This compound can be classified as a benzyl halide. [2] [3] Xylylene dichloride is used as a vulcanizing agent to harden rubbers. It catalyzes the crosslinking of phenolic resins. [2]

The polymerization of [2,2]-paracyclophanes involves technologically p-xylylene molecule (the monomer) which originates from the cyclophanes after the pyrolysis in high temeperature. P-xylylene (3,6-Bis(methylene)-1,4-cyclohexadiene, also called p-quinodimethane) is a simple hydrocarbon molecule of both theoretical and commercial interest.

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 (CH3)2C6H4.

In organic chemistry, a xylylene (sometimes quinone-dimethide) is any of the constitutional isomers having the formula C6H4(CH2)2. These compounds are related to the corresponding quinones and quinone methides by replacement of the oxygen atoms by CH2 groups. ortho- and para-xylylene are best known, although neither is stable in solid or liquid ...
