Cyclic hydrocarbons; o-xylene

HS v2017 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 broader manufacturing and construction sectors, making it an integral part of the global economy.

Production process

O-xylene is primarily produced through the catalytic reforming of petroleum fractions, a process that involves the rearrangement of hydrocarbon molecules to increase the proportion of aromatic compounds. This is typically done in specialized refineries and petrochemical plants, where the raw materials undergo a series of distillation, separation, and purification steps to isolate the desired o-xylene product.

Production inputs

The main inputs required for the production of o-xylene include crude oil or natural gas liquids, which serve as the primary feedstock. Additionally, the process requires specialized catalysts, energy sources (such as heat and electricity), and various processing equipment, including distillation columns, reactors, and separation units.

Production outputs

The primary output of HS code 290241 is o-xylene, which is then used as a feedstock for the production of a wide range of other chemicals and materials. Some of the key downstream industries that consume o-xylene include the manufacture of 290243 phthalic anhydride, 390120 polyethylene terephthalate, and various other plastics, resins, and organic intermediates.
