Cyclic hydrocarbons; ethylbenzene

HS v2017 Code: 290260

About cyclic hydrocarbons; ethylbenzene

HS code 290260 covers the classification of cyclic hydrocarbons, with a specific focus on ethylbenzene. This organic chemical compound is a crucial raw material in the production of various industrial and consumer goods, making it an important component of the broader petrochemical industry. Ethylbenzene's versatility and widespread applications across diverse sectors contribute to its significance within the global economy.

Production process

The primary production method for ethylbenzene involves the alkylation of benzene with ethylene. This process typically takes place in the presence of a catalyst, such as aluminum chloride or zeolites, to facilitate the chemical reaction and improve efficiency. The resulting ethylbenzene is then separated and purified through distillation or other separation techniques to meet the required purity standards for various applications.

Production inputs

The main inputs required for the production of ethylbenzene under HS code 290260 include benzene and ethylene, which are both derived from the refining and processing of crude oil and natural gas. Additionally, the production process may require specialized equipment, such as reactors, distillation columns, and purification systems, as well as energy sources and various catalysts or additives to optimize the reaction and separation stages.

Production outputs

The primary output of HS code 290260 is ethylbenzene, which is a widely used chemical intermediate. Ethylbenzene is a key precursor in the production of 290360 styrene, a monomer used in the manufacture of various polymers, including 390300 polystyrene and 390950 styrene-butadiene rubber. These downstream products find applications in a diverse range of industries, such as packaging, construction, automotive, and consumer goods.
