colourless liquidChEBI: A xylene with methyl groups at positions 1 and 4.p-xylene is an aromatic hydrocarbon based on benzene with two methyl substituents with the chemical formula C8H10 or C6H4(CH3)2. It is one of the three isomers of dimethylbenzene known collectively as xylenes. The “p” stands for para, identifying that he two methyl groups in p-xylene occupy the diametrically opposite substituent positions 1 and 4. p-Xylene is a colorless, flammable liquid practically insoluble in water. p-
