Cyclic hydrocarbons; cyclohexane

HS v2022 Code: 290211

About cyclic hydrocarbons; cyclohexane

HS code 290211 covers the classification of cyclohexane, a cyclic hydrocarbon compound. Cyclohexane is a versatile chemical with a wide range of industrial applications, making it an important commodity in the global chemical industry. It serves as a key raw material for the production of various downstream products, contributing significantly to the broader economy.

Production process

Cyclohexane is primarily produced through the catalytic hydrogenation of benzene, a process that involves the addition of hydrogen to the benzene ring to form the saturated cyclohexane molecule. This reaction is typically carried out under high temperature and pressure conditions, with the use of metal catalysts to facilitate the conversion.

Production inputs

The main inputs required for the production of cyclohexane include benzene, hydrogen, and various catalysts such as nickel or platinum. Additionally, the process requires specialized equipment, such as reactors, distillation columns, and heat exchangers, to effectively carry out the hydrogenation and purification steps.

Production outputs

The primary output of HS code 290211 is cyclohexane, which is then used as a feedstock for the production of other chemicals and materials. Cyclohexane is a key intermediate in the manufacture of 290712 adipic acid, an important precursor for 390610 nylon 6. It is also used in the production of 290250 styrene, a monomer for various polymers, as well as in the synthesis of other organic compounds.
