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

HS v2017 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 crucial organic compound used in a wide range of industries. As an acyclic aldehyde without any other oxygen function, acetaldehyde serves as a key intermediate in the production of various chemicals, pharmaceuticals, and consumer goods. Its importance within the broader chemical industry cannot be overstated, as it underpins the manufacturing of numerous essential products that are integral to modern society.

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. The reaction takes place at elevated temperatures, and the resulting acetaldehyde is then purified and refined for various applications.

Production inputs

The main inputs required for the production of acetaldehyde include ethanol, which serves as the primary raw material, as well as catalysts such as copper or silver. Additionally, the process requires access to air or oxygen, as well as specialized equipment and machinery to facilitate the catalytic oxidation and subsequent purification of the final product.

Production outputs

The primary output of HS code 291212 is acetaldehyde, which is then consumed by a wide range of industries. Acetaldehyde is a key intermediate in the production of 291411 acetic acid, 291440 butyraldehyde, and 291450 other aldehydes, among other important chemicals. It is also used in the synthesis of various pharmaceuticals, flavors, and fragrances, as well as in the production of 292100 amine-function compounds.
