CAS: 95-47-6
Orthoxylene (o-Xylene) is a clear, flammable liquid that belongs to the
hydrocarbon family. It is one of three variations (isomers) of dimethylbenzene.
Thanks to its unique molecular structure, it is particularly effective in
manufacturing phthalic anhydride, a key component used in many chemical
processes. This compound plays a critical role in producing resins, solvents,
and other industrial materials. Orthoxylene is known for its reliability in
large-scale chemical production, distinguishing it from other xylene isomers
due to its more targeted industrial applications.

Application in the Plastic & Rubber Industry
Orthoxylene plays a significant role in synthesizing phthalic anhydride
that is a core feedstock for plasticizer via the reaction with ethylene
dichloride in the Plastic & Rubber sector. Plasticizers are added to
plastics to make them more flexible and long-lasting, absolutely needed for
general-use products. In addition, Orthoxylene can be used in the production of
polyester resins which is important for automotive and construction fiberglass
composite. Its synthesis in the manufacture of synthetic rubbers not only
endows a degree of durability to the products but actually makes it compulsory
for the creation of long lasting, high-performance rubber.
Other Industries Where It Is Applied
● Oil
& Gas: o-Xylene is used in solvents and refining processes to enhance oil
extraction efficiency and product purity.
● Construction:
It plays a crucial role in alkyd resins for protective and decorative coatings
used in construction materials.
● Coatings,
Adhesives, Sealants, and Elastomers (CASE): Extensively utilized in the
manufacture of high-performance adhesives, sealants and coatings targeted for
industrial as well as consumer applications.
● Lubricants
and Greases: Imperative for their lubricity and life performance in the
extreme.
● Agriculture:
Some of Orthoxylene derivatives are used for agrochemicals, including
pesticides and herbicides.
