About epoxides, epoxyalcohols, epoxyphenols and epoxyethers; with a three-membered ring and their halogenated, sulphonated, nitrated or nitrosated derivatives, 1-chloro-2,3-epoxypropane (epichlorohydrin)

HS code 291030 covers a group 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 epoxides and their derivatives have a wide range of industrial applications, making this a significant sector within the broader chemical industry.

Production process

The production of the compounds covered under HS code 291030 typically involves the epoxidation of olefins, alcohols, phenols, or ethers. This is often achieved through the use of peroxyacids or other oxidizing agents. The resulting epoxides may then undergo further chemical reactions to introduce the desired halogenated, sulphonated, nitrated, or nitrosated functional groups.

Production inputs

The main inputs required for the production of the compounds in this HS code include olefins, alcohols, phenols, and ethers as raw materials, as well as various oxidizing agents and other chemical reagents. Additionally, specialized production equipment, such as reactors, distillation columns, and purification systems, are necessary to carry out the various synthesis and purification steps.

Production outputs

The compounds produced under HS code 291030 have a wide range of applications, including as intermediates in the production of 390110 polyethylene, 390120 polyproplylene, and other polymers, as well as in the manufacture of 290531 ethylene glycol and other specialty chemicals. The epoxides and their derivatives may also be used as solvents, plasticizers, and in the production of epoxy resins.
