xylene
xylene Chem. (ˈzaɪliːn) [f. Gr. ξύλον wood + -ene.] A mixture of three isomeric hydrocarbons having the formula C8H10 = C6H4(CH3)2, obtained as a volatile colourless liquid from wood-spirit or coal-naphtha; any one of these three hydrocarbons: systematically named dimethylbenzene.

Xylene
Commercial or laboratory-grade xylene produced usually contains about 40–65% of m-xylene and up to 20% each of o-xylene, p-xylene and ethylbenzene.

Why is Xylene a Good Solvent? | Education - Seattle PI
Science. By John Brennan. Xylene is a colorless mixture of chemically-related hydrocarbons that often finds use as a solvent for paints and printing inks. It's very good at dissolving compounds that dissolve poorly in water, which is why it is so useful. Its ability to do so stems from its properties and its chemical structure.

Xylene cyanol
Once mixed with the sample, the concentration of xylene cyanol is typically about 0.005% to 0.03%. Xylene cyanol on a 6% polyacrylamide gel migrates at the speed of a 140 base pair DNA fragment. wikipedia.org

P-Xylene
p-Xylene (para-xylene) is an aromatic hydrocarbon. It is one of the three isomers of dimethylbenzene known collectively as xylenes. The p-xylene is then separated out in a series of distillation, adsorption or crystallization and reaction processes from the m-xylene, o-xylene, and ethylbenzene wikipedia.org

M-Xylene
m-Xylene (meta-xylene) is an aromatic hydrocarbon. It is one of the three isomers of dimethylbenzene known collectively as xylenes. It is in the positions of the two methyl groups, their arene substitution pattern, that it differs from the other isomers, o-xylene and p-xylene. wikipedia.org

CN110746255A - Method for preparing p-xylene from crude benzene ...
The invention relates to a method for directly producing p-xylene from crude benzene. The crude benzene is used as raw material to directly carry out alkylation reaction to obtain a primary product containing p-xylene with higher concentration, and then low-temperature hydrogenation and separation refining are carried out to obtain pure p-xylene.
