HS v2022 Code: 290920

About ethers; cyclanic, cyclenic or cycloterpenic and their halogenated, sulphonated, nitrated or nitrosated derivatives

HS code 290920 covers a diverse range of organic compounds known as ethers. These compounds play a crucial role in various industries, including pharmaceuticals, solvents, and specialty chemicals. Ethers with cyclanic, cyclenic, or cycloterpenic structures, along with their halogenated, sulphonated, nitrated, or nitrosated derivatives, are particularly important in the global chemical trade and manufacturing processes.

Production process

The production of HS 290920 ethers typically involves a multi-step process. The first step is the synthesis of the base ether compound, often through the reaction of an alcohol with an alkyl halide or the dehydration of an alcohol. Subsequent steps may involve the introduction of various functional groups, such as halides, sulphonic acids, or nitro groups, to create the desired derivatives. These modifications are achieved through a range of chemical reactions, including halogenation, sulfonation, and nitration.

Production inputs

The production of HS 290920 ethers requires a variety of raw materials, including alcohols, alkyl halides, and other organic compounds. Additionally, specialized equipment, such as reactors, distillation columns, and purification systems, are necessary for the synthesis and refinement of these chemicals. Skilled personnel with expertise in organic chemistry and chemical engineering are also crucial for the efficient and safe operation of the manufacturing process.

Production outputs

HS 290920 ethers find applications in numerous industries, including 290511 Methanol, 290512 (Propan-1-ol (Propyl alcohol) and Propan-2-ol (Isopropyl alcohol)), and 290513 (Butan-1-ol (n-Butyl alcohol)), which may consume these compounds as solvents, intermediates, or additives. Additionally, these ethers can be further processed to create a wide range of other chemical products, such as pharmaceuticals, plastics, and specialty coatings, making them an important part of the global chemical supply chain.
