HS v2022 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, finding widespread use across a variety of manufacturing and processing industries. As an acyclic ketone without any other oxygen functions, MIBK exhibits unique solvency and chemical properties that make it a valuable component in numerous products and processes.

Production process

MIBK is typically produced through the catalytic hydrogenation of 4-methylpentan-3-one, which is derived from the aldol condensation of acetone and isobutyraldehyde. The reaction is carried out under controlled temperature and pressure conditions, often using supported metal catalysts to optimize yield and selectivity. Distillation and purification steps are then employed to obtain the desired high-purity MIBK product.

Production inputs

The primary raw materials required for MIBK production are acetone and isobutyraldehyde. Specialized catalysts, such as supported palladium or platinum, are also essential inputs. Additionally, the process requires access to reliable sources of hydrogen gas, as well as utilities like steam, cooling water, and electricity to power the manufacturing equipment.

Production outputs

MIBK is a versatile chemical that finds application as a solvent, an intermediate, and a component in various formulations. It is widely used in the production of paints, coatings, adhesives, and cleaning agents. MIBK may also be consumed by industries producing 290511 Methanol, 290512 (Propan-1-ol (propyl alcohol) and propan-2-ol (isopropyl alcohol)), and 290513 (Butan-1-ol (n-butyl alcohol)), as it can serve as a precursor or additive in the manufacture of these other organic compounds.
