Mixed-Xylene
PRODUCT DESCRIPTION:
Mixed xylenes are the
second-most-important aromatic product in terms of world consumption for
chemical manufacture, ranking behind benzene
and ahead of toluene. Mixed xylenes refers to the equilibrium mixture of four
isomers with the same C8H10 chemical formula. The
isomers in order of natural occurrence are meta-xylene, ortho-xylene,
para-xylene, and ethylbenzene.
Xylenes are produced with different
processes. When in refineries, oil cuts enter the reforming units, aromatic
compounds comprise a great proportion of the outflow material. Separating this
flow into its components, accounts for more than 70 percent of global xylene
supply. Also in the steam cracking process in olefin units, some quantity of
Mixed Xylene is produced. In addition, disproportioning Toluene into Benzene
and Xylene and treating Pyrolysis Gasoline are also different ways to produce
Mixed Xylene.
PRODUCT APPLICATION:
• Production of para-xylene, ortho-xylene and meta-xylene – the most important application of mixed xylene is to separate different isomers of xylene, i.e. para-xylene, ortho-xylene and meta-xylene. They are respectively consumed in production of PTA, Phthalic acid and IsoPhthalic acid. Their final use include production of PET, PVC Plasticizer and Surface Coatings.
•
Gasoline blend – Mixed xylene due to its high octane number and low vapor pressure, is a great compound for blending with gasoline.
•
Chemical Industries- Mixed xylene is also used, however in small quantities, for producing paint and solvents.
