Cyclic hydrocarbons; m-xylene

HS v2022 Code: 290242

About cyclic hydrocarbons; m-xylene

HS code 290242 covers the classification of m-xylene, a cyclic hydrocarbon compound. This chemical is an important industrial feedstock, with applications in the production of various other chemicals, plastics, and solvents. As a key component in the petrochemical industry, m-xylene plays a vital role in supporting a wide range of manufacturing and processing activities across the global economy.

Production process

M-xylene is typically produced through the catalytic reforming of naphtha, a petroleum fraction. This process involves the rearrangement of hydrocarbon molecules to increase the aromatic content, with m-xylene being one of the desired outputs. Alternatively, m-xylene can also be extracted from mixed xylene streams, which are byproducts of other petrochemical processes.

Production inputs

The primary inputs for the production of m-xylene include naphtha or mixed xylene streams, as well as various catalysts and process equipment. Refineries and petrochemical plants are the main facilities responsible for the manufacturing of m-xylene, requiring access to crude oil or natural gas feedstocks, as well as specialized distillation and catalytic conversion technologies.

Production outputs

M-xylene is an important intermediate chemical that is further processed and consumed by a variety of downstream industries. It is used in the production of 290243 phthalic anhydride, which is a key raw material for the manufacture of plasticizers, resins, and other chemicals. M-xylene is also a precursor for the synthesis of 290243 isophthalic acid, an important component in the production of polyester resins and engineering plastics.
