m-xylene
Sign in to saveAlso known as meta-xylene, m-xylol, 1,3-dimethylbenzene, 3-xylene, m-dimethylbenzene, m-methyltoluene, 1,3-Dimethylbenzol, 1,3-xylene
'''m-Xylene (meta-xylene') is an aromatic hydrocarbon. It is one of the three isomers of dimethylbenzene known collectively as xylenes. The m- stands for meta-, indicating that the two methyl groups in m-xylene occupy positions 1 and 3 on a benzene ring. 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. All have the same chemical formula C6H4(CH3)2. All xylene isomers are colorless and highly flammable.

All xylene isomers are colorless and highly flammable.
==Production and use== Petroleum contains about 1 weight percent xylenes. The meta isomer can be isolated from a mix of xylenes by the partial sulfonation (to which other isomers are less prone) followed by removal of unsulfonated oils and steam distillation of the sulfonated product.
