Cyclic hydrocarbons; cumene

HS v2017 Code: 290270

About cyclic hydrocarbons; cumene

HS code 290270 covers cyclic hydrocarbons, with a specific focus on the compound cumene. Cyclic hydrocarbons are an important class of organic compounds that have a wide range of industrial applications, from the production of fuels and solvents to the manufacture of various plastics and resins. Cumene, in particular, is a key intermediate in the production of phenol and acetone, which are widely used in the chemical industry.

Production process

Cumene is typically produced through the alkylation of benzene with propylene. This process involves the use of an acidic catalyst, such as aluminum chloride or boron trifluoride, to facilitate the reaction between the two reactants. The resulting cumene is then separated and purified through distillation and other separation techniques.

Production inputs

The main inputs required for the production of cumene under HS code 290270 include benzene and propylene as the primary raw materials, as well as various catalysts and energy sources to power the production process. Specialized equipment, such as reactors, distillation columns, and purification systems, are also necessary for the efficient manufacture of cumene.

Production outputs

The primary output of HS code 290270 is cumene, which is then used as a feedstock for the production of 290711 phenol and 291411 acetone. These two chemicals are widely used in the production of various plastics, resins, and other industrial chemicals, making cumene an important intermediate in the broader chemical industry.
