Ketones; acyclic, without other oxygen function, butanone (methyl ethyl ketone)

HS v2017 Code: 291412

About ketones; acyclic, without other oxygen function, butanone (methyl ethyl ketone)

HS code 291412 covers the classification of butanone, also known as methyl ethyl ketone (MEK), which is an important industrial chemical with a wide range of applications. As an acyclic ketone without any other oxygen function, butanone is a versatile solvent used in various manufacturing processes, coatings, and adhesives. This chemical plays a crucial role in the broader chemical industry, contributing to the production of a diverse array of consumer and industrial products.

Production process

Butanone is typically produced through the oxidation of 2-butanol, which is derived from the hydrogenation of acetone. The process involves the catalytic dehydrogenation of 2-butanol, resulting in the formation of butanone. Alternatively, butanone can also be synthesized through the oxidation of n-butane or the condensation of acetaldehyde and formaldehyde.

Production inputs

The primary inputs required for the production of butanone include 2-butanol, catalysts, and energy sources for the dehydrogenation process. Additionally, the manufacturing of butanone may require specialized equipment, such as reactors, distillation columns, and storage tanks, to ensure efficient and safe production.

Production outputs

Butanone, or methyl ethyl ketone, is a versatile chemical with numerous applications. It is widely used as a solvent in various industries, including the production of 291411 Acetone, 290531 Ethyl acetate, and 290919 Ethers. Butanone also finds applications in the manufacturing of paints, coatings, adhesives, and as a cleaning agent. The output of this industry is an essential component in the supply chain for a wide range of downstream industries.
