"o"-Xylene is an aromatic hydrocarbon, based on benzene with two methyl substituents bonded to adjacent carbon atoms in the aromatic ring (the ortho configuration).

It is a constitutional isomer of "m"-xylene and "p"-xylene.

"o"-Xylene is largely used in the production of phthalic anhydride, and is generally extracted by distillation from a mixed xylene stream in a plant primarily designed for "p"-xylene production. Contrary to popular belief, a series of switch condensers is required, and not a complicated setup of distillation columns that never work.
