Cyclic hydrocarbons; cyclohexane

HS v2017 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 feedstock for the production of various downstream chemicals and is widely used in the manufacturing of plastics, solvents, and other essential products.

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 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 other processing units, 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 a wide range of downstream products. These include 290250 cyclohexanone, 290260 cyclohexanol, and various types of plastics, such as 390120 polyethylene, 390950 polycarbonates, and 390940 cellulose acetate. Cyclohexane is also used as a solvent in the chemical and pharmaceutical industries.
