Sign in to saveAlso known as 1,2-dimethylbenzene, ortho-xylene, o-xylol, 2-xylene, 3,4-xylene, 1,2-Dimethylbenzol, 1,2-xylene
'''o-Xylene (ortho-xylene') is an aromatic hydrocarbon with the formula C6H4(CH3)2, with two methyl substituents bonded to adjacent carbon atoms of a benzene ring (the ortho configuration). It is a constitutional isomer of m-xylene and p-xylene, the mixture being called xylene or xylenes. o''-Xylene is a colourless slightly oily flammable liquid.

'''o-Xylene (ortho-xylene') is an aromatic hydrocarbon with the formula C6H4(CH3)2, with two methyl substituents bonded to adjacent carbon atoms of a benzene ring (the ortho configuration). It is a constitutional isomer of m-xylene and p-xylene, the mixture being called xylene or xylenes. o-Xylene is a colourless slightly oily flammable liquid.
==Production and use== Petroleum contains about one weight percent xylenes. Most o-xylene is produced by cracking petroleum, which affords a distribution of aromatic compounds, including xylene isomers. m-Xylene is isomerized to o-xylene. Net production was approximately 500,000 tons in the year 2000.
