About epoxides, epoxyalcohols, epoxyphenols and epoxyethers; with a three-membered ring and their halogenated, sulphonated, nitrated or nitrosated derivatives; oxirane (ethylene oxide)

HS code 291010 covers a range of organic chemical compounds known as epoxides, epoxyalcohols, epoxyphenols, and epoxyethers. These compounds are characterized by a three-membered ring structure and can be further modified through halogenation, sulphonation, nitration, or nitrosation. The chemicals under this code have diverse applications across various industries, making them an important part of the global chemical trade.

Production process

The production of the chemicals under HS code 291010 typically involves the epoxidation of olefins, such as ethylene, using oxidizing agents like hydrogen peroxide or peracids. The epoxidation process creates the characteristic three-membered ring structure. Further modifications, such as halogenation or sulphonation, may be carried out depending on the desired end-product.

Production inputs

The main inputs required for the production of the chemicals under HS code 291010 include olefins (such as ethylene), oxidizing agents (e.g., hydrogen peroxide, peracids), and various halogenating or sulphonating agents. Additionally, specialized production equipment, such as reactors, distillation columns, and purification systems, are necessary for the manufacturing process.

Production outputs

The chemicals produced under HS code 291010 have a wide range of applications, including the manufacture of 390110 Polyethylene with a specific gravity of less than 0.94, 390120 Polyethylene with a specific gravity of 0.94 or more, 390130 Ethylene-vinyl acetate copolymers, and various other polymers, as well as in the production of pharmaceuticals, personal care products, and industrial solvents.
