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

HS v2022 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), a widely used industrial chemical. As an acyclic ketone without any other oxygen function, butanone is an important solvent and chemical intermediate employed across a diverse range of industries, from paints and coatings to adhesives and pharmaceuticals. Its versatility and high demand make it a crucial component in the global chemical supply chain.

Production process

Butanone is primarily produced through the catalytic oxidation of 2-butanol. This process involves the controlled oxidation of 2-butanol, typically using air or oxygen as the oxidizing agent and a metal catalyst such as copper or chromium. The resulting butanone is then purified through distillation to meet the required purity and quality standards for commercial use.

Production inputs

The main inputs required for the production of butanone include 2-butanol as the primary raw material, as well as air or oxygen, catalysts, and energy sources to power the oxidation and distillation processes. Specialized equipment such as reactors, distillation columns, and storage tanks are also essential for the efficient manufacture of butanone.

Production outputs

Butanone, as classified under HS code 291412, is a versatile chemical with a wide range of applications. It is commonly used as a solvent in various industries, including 330520 paints and coatings, 350610 adhesives, and 300490 pharmaceuticals. Butanone is also an important chemical intermediate for the production of other compounds, such as 291470 methyl isobutyl ketone and 291511 acetic acid.
