HS v2017 Code: 291413

About ketones; acyclic, without other oxygen function, 4-methylpentan-2-one (methyl isobutyl ketone)

HS code 291413 covers the classification of 4-methylpentan-2-one, also known as methyl isobutyl ketone (MIBK). This organic compound is an important industrial solvent and chemical intermediate used in a wide range of applications across various industries. As an acyclic ketone, MIBK plays a crucial role in the production of paints, coatings, adhesives, and other chemical formulations, making it a vital component in the global manufacturing landscape.

Production process

The primary production method for MIBK involves the catalytic hydrogenation of acetone, a process that converts the raw material into the desired ketone. This reaction is typically carried out under controlled temperature and pressure conditions, often with the aid of metal catalysts to improve efficiency and yield. The resulting MIBK is then purified and refined to meet the specific quality and purity requirements of its intended applications.

Production inputs

The main inputs required for the production of MIBK include acetone as the primary raw material, as well as hydrogen gas, catalysts, and various processing equipment such as reactors, distillation columns, and storage tanks. The availability and cost of these inputs can significantly impact the overall production and supply of MIBK in the global market.

Production outputs

The primary output of HS code 291413 is 4-methylpentan-2-one, or methyl isobutyl ketone (MIBK). This versatile chemical is widely used as a solvent in the production of 321110 Paints and varnishes, 350610 Adhesives, and various other chemical formulations. MIBK may also be further processed or combined with other substances to create a range of downstream products classified under different HS codes, such as 290590 Other acyclic alcohols and 291429 Ketones, cyclic, without other oxygen function, n.e.c. in heading 2914.
