Aldehydes; acyclic, without other oxygen function, ethanal (acetaldehyde)

HS v2022 Code: 291212

About aldehydes; acyclic, without other oxygen function, ethanal (acetaldehyde)

HS code 291212 covers the classification of ethanal, also known as acetaldehyde, which is a key aldehyde compound with a wide range of industrial applications. As an acyclic aldehyde without any other oxygen functions, acetaldehyde is an important building block for various chemical processes and products. This code sits within the broader category of organic chemicals, playing a vital role in the global chemical industry and international trade.

Production process

Acetaldehyde is primarily produced through the catalytic oxidation of ethanol. This process involves the controlled oxidation of ethanol using air or oxygen in the presence of a catalyst, typically copper or silver-based. The reaction takes place at elevated temperatures, converting the ethanol into acetaldehyde. Distillation and purification steps are then used to obtain the desired purity levels of the final product.

Production inputs

The main inputs required for the production of acetaldehyde under HS code 291212 include ethanol as the primary raw material, as well as catalysts such as copper or silver compounds. Specialized production equipment, such as reactors, distillation columns, and purification systems, are also essential for the manufacturing process.

Production outputs

Acetaldehyde produced under HS code 291212 has a wide range of applications and is consumed by various other industries. It is used as an intermediate in the production of other organic chemicals, including 291219 acyclic aldehydes, without other oxygen function, 291531 ethyl acetate, and 292700 hydrogen cyanide. Acetaldehyde is also utilized in the synthesis of pharmaceuticals, flavors, and fragrances.
