Mix Xylene, CAS No. : 1330-20-7

The term mixed xylenes refers to the equilibrium mixture of four isomers with the same C₈H₁₀ chemical formula—para-xylene, ortho-xylene, meta-xylene, and ethylbenzene.

Mixed xylene is used as solvent for paint and pesticide. It is also a raw material for orthoxylene (phthalic anhydride), metaxylene (isophthalic acid), paraxylene (terephthalic acid) and ethylbenzene (styrene monomer).Commercial or mixed xylene usually contains about 40-65% m-xylene and up to 20% each of o-xylene and p-xylene and ethylbenzene. Xylenes are released into the atmosphere as fugitive emissions from industrial sources, from auto exhaust, and through volatilization from their use as solvents.
