Cyclic hydrocarbons; m-xylene

HS v2017 Code: 290242

About cyclic hydrocarbons; m-xylene

HS code 290242 covers the classification of m-xylene, a cyclic hydrocarbon compound. M-xylene is an important industrial chemical with a wide range of applications, including the production of dyes, solvents, and various other chemical intermediates. As a key component in the petrochemical industry, m-xylene plays a vital role in the broader economy, supporting the manufacturing of a diverse array of consumer and industrial products.

Production process

M-xylene is typically produced through the catalytic reforming of petroleum fractions, a process that involves the rearrangement of hydrocarbon molecules to increase the proportion of aromatic compounds. The specific production techniques may involve distillation, extraction, and purification steps to isolate the m-xylene fraction from the broader hydrocarbon stream.

Production inputs

The primary inputs required for the production of m-xylene include crude oil or natural gas liquids, which serve as the feedstock, as well as specialized catalysts and processing equipment. Refineries and petrochemical plants are the main facilities responsible for the large-scale production of m-xylene, relying on sophisticated distillation and separation technologies to extract the desired compound.

Production outputs

M-xylene is a versatile chemical that finds application in the manufacture of various downstream products. It is commonly used as a raw material for the production of 290243 phthalic anhydride, an important industrial chemical used in the synthesis of plasticizers, resins, and other materials. M-xylene may also be further processed to yield other aromatic compounds, such as 290243 isophthalic acid, which are used in the production of polyester resins and other specialty chemicals.
