XYLENES
Xylenes - para-xylene, ortho-xylene and meta-xylene - are extracted or distilled from gasoline refining. They can also be produced from toluene using the disproportionation process. Xylene is mainly supplied as a mixed stream, although various processes are used to separate the individual isomers for specific end-uses.
