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

HS code 291050 covers a range of chemical compounds known as epoxides, epoxyalcohols, epoxyphenols, and epoxyethers. These substances are characterized by a three-membered ring structure and can be further modified through halogenation, sulphonation, nitration, or nitrosation. This class of chemicals is widely used in various industries, including plastics, resins, and pharmaceuticals, making it an important component of the global chemical trade.

Production process

The production of the chemicals covered under HS code 291050 typically involves a series of chemical reactions. The key steps often include the epoxidation of olefins, the reaction of epoxides with alcohols or phenols, and the subsequent modification of the resulting compounds through halogenation, sulphonation, nitration, or nitrosation. These processes are carried out in specialized chemical plants using a range of equipment, such as reactors, distillation columns, and purification systems.

Production inputs

The main inputs required for the production of the chemicals under HS code 291050 include various organic compounds, such as olefins, alcohols, and phenols, as well as halogenating, sulphonating, nitrating, or nitrosating agents. Additionally, the industry relies on specialized equipment, including reactors, distillation columns, and purification systems, as well as a skilled workforce with expertise in chemical engineering and process optimization.

Production outputs

The chemicals produced under HS code 291050 are used as intermediates in the manufacture of a wide range of products, including 390100 Polymers of ethylene, in primary forms, 390200 Polymers of styrene, in primary forms, and 300490 Medicaments consisting of mixed or unmixed products for therapeutic or prophylactic uses, put up in measured doses or in forms or packings for retail sale. These epoxide-based compounds are particularly valuable in the production of plastics, resins, and pharmaceutical drugs.
