Metaxylene

Meta-xylene, also known as 1,3-dimethylbenzene, is an aromatic hydrocarbon and one of the three isomers of xylene. It occurs with other xylene isomers in mixed xylene streams derived from crude oil processing and catalytic reforming. In industry, meta-xylene is typically separated from a mixture of xylenes and is often produced alongside ortho- and para-xylene during the aromatics recovery and upgrading steps.

Meta-xylene is a colorless to pale straw liquid that has the characteristic sweet odor of xylenes. It

In addition to its role as a solvent, meta-xylene is a key feedstock for the production of
