Cyclic hydrocarbons; o-xylene

HS v2022 Code: 290241

About cyclic hydrocarbons; o-xylene

HS code 290241 covers the classification of o-xylene, a cyclic hydrocarbon compound. O-xylene is an important industrial chemical with a wide range of applications, particularly in the production of various plastics, resins, and other organic compounds. As a key component in the petrochemical industry, o-xylene plays a crucial role in supporting the manufacturing of a diverse array of consumer and industrial products, making it an integral part of the global economy.

Production process

O-xylene is primarily produced through the catalytic reforming of petroleum fractions. This process involves the rearrangement and dehydrogenation of naphtha feedstocks to yield a mixture of aromatic hydrocarbons, including o-xylene. Subsequent distillation and purification steps are then used to isolate the o-xylene fraction from the broader aromatic stream.

Production inputs

The main inputs required for the production of o-xylene include crude oil or natural gas liquids, which serve as the feedstock for the catalytic reforming process. Additionally, specialized catalysts, energy sources, and various processing equipment are necessary to facilitate the conversion of the feedstock into the desired o-xylene product.

Production outputs

The primary output of HS code 290241 is o-xylene, which is then consumed by a variety of downstream industries. O-xylene is used as a raw material in the production of 290243 phthalic anhydride, a key ingredient in the manufacture of plastics, resins, and other polymeric materials. It also finds applications in the synthesis of various organic chemicals, solvents, and other industrial compounds.
