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

HS code 291020 covers a group of organic compounds known as epoxides, which are characterized by a three-membered ring containing one oxygen atom. These compounds are widely used in the chemical industry, finding applications in the production of various polymers, resins, and specialty chemicals. Their versatility and unique properties make them an essential part of the global chemical supply chain.

Production process

The primary production method for epoxides under HS code 291020 is the epoxidation of olefins, which involves the addition of an oxygen atom to the carbon-carbon double bond. This process can be carried out using various oxidizing agents, such as peracids, hydrogen peroxide, or molecular oxygen. The specific techniques and conditions used depend on the target epoxide and the desired level of purity and selectivity.

Production inputs

The main inputs required for the production of epoxides under HS code 291020 include olefins (such as propylene), oxidizing agents, and various catalysts and solvents. Specialized equipment, such as reactors, distillation columns, and purification systems, are also essential for the efficient and safe production of these compounds.

Production outputs

The primary outputs of the industry covered by HS code 291020 are the epoxides themselves, which can be further processed or used as intermediates in the production of a wide range of downstream products. These include 390100 Polymers of ethylene, in primary forms, 390200 Polymers of propylene or of other olefins, in primary forms, and 390730 Epoxide resins, in primary forms.
