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. One of the key products in this category is epichlorohydrin, which is an important industrial chemical with a wide range of applications. The 291030 industry plays a crucial role in the production of various downstream products, making it an integral part of the broader chemical manufacturing sector.

Production process

The production of the chemicals covered under HS code 291030 typically involves a multi-step process. The starting point is often the reaction of propylene with chlorine to form 1-chloro-2,3-epoxypropane (epichlorohydrin). This is then further processed through a series of chemical reactions to produce the desired epoxide, epoxyalcohol, epoxyphenol, or epoxyether compounds. The specific techniques used may vary depending on the target product, but often include distillation, extraction, and purification steps to ensure the desired purity and quality of the final output.

Production inputs

The main inputs required for the 291030 industry include propylene, chlorine, and other raw materials such as alcohols, phenols, and ethers, depending on the specific product being manufactured. Additionally, the industry relies on specialized production equipment, including reactors, distillation columns, and purification systems. Energy sources, such as electricity and steam, are also crucial inputs for the various stages of the production process.

Production outputs

The chemicals produced under HS code 291030 are used as intermediates in the manufacture of a wide range of downstream products. For example, epichlorohydrin is a key precursor for the production of epoxy resins 390730 Epoxide resins, which are used in paints, coatings, and adhesives. Other 291030 products may find applications in the production of pharmaceuticals, pesticides, and other specialty chemicals. The outputs of this industry are often consumed by manufacturers under codes such as 380810 Insecticides, rodenticides, fungicides, herbicides, anti-sprouting products and plant-growth regulators, disinfectants and similar products, 390720 Polymers of propylene or other olefins, in primary forms, and 290920 Epoxides, epoxyalcohols, epoxyphenols and epoxyethers, with a three-membered ring, and their halogenated, sulphonated, nitrated or nitrosated derivatives.

Revisions to 291030
