Cyclic hydrocarbons; cumene
HS v2022 Code: 290270
About cyclic hydrocarbons; cumene
HS code 290270 covers cyclic hydrocarbons, specifically the compound cumene. Cumene is an important industrial chemical with a wide range of applications, making it a crucial component in the broader petrochemical industry. As a precursor to other valuable chemicals, cumene plays a significant role in the manufacturing of various products that are essential to modern society.
Production process
Cumene is primarily produced through the alkylation of benzene with propylene. This process involves the reaction of benzene and propylene under specific temperature and pressure conditions, catalyzed by either solid or liquid catalysts. The resulting cumene is then separated and purified through distillation and other separation techniques to meet the required purity standards for various industrial applications.
Production inputs
The main inputs for the production of cumene under HS code 290270 include benzene and propylene, which are both derived from the petrochemical industry. Additionally, the production process requires specialized equipment, such as reactors, distillation columns, and other processing units, as well as energy sources, such as steam or electricity, to power the manufacturing operations.
Production outputs
The primary output of HS code 290270 is cumene, which is a valuable intermediate chemical used in the production of other important compounds, such as 290420 phenol and 291470 acetone. Cumene is also used directly in the manufacture of certain resins, solvents, and other specialty chemicals. The outputs of this industry are essential inputs for a wide range of downstream industries, including plastics, pharmaceuticals, and construction materials.
