High Purity CAS 106-42-3 p-Xylene Chemical Solvent

CAS 106-42-3 p-Xylene's unique structure makes it an indispensable compound, primarily dominating the polyester value chain:

• Terephthalic Acid (PTA) & Dimethyl Terephthalate (DMT) Production: This is the overwhelmingly largest application. p-Xylene is oxidized to produce PTA or esterified to DMT, both of which are key monomers for polyester.

• Polyester Fibers & Films: PTA and DMT are used to manufacture polyethylene terephthalate (PET) polymers, which are then spun into polyester fibers for textiles and industrial applications, and cast into films for packaging and other uses.

• PET Resins & Plastic Bottles: PET is widely used for producing lightweight, recyclable plastic bottles for beverages, as well as containers for food and other consumer goods.

• Solvent: While its primary use is as a feedstock, p-Xylene can also serve as a solvent in specialized applications, similar to other xylene isomers.
