HS v2022 Code: 291439

About ketones; aromatic, (without other oxygen function), excluding phenylacetone (phenylpropan-2-one)

HS code 291439 covers a group of aromatic ketones, which are organic compounds containing a carbonyl group (C=O) attached to an aromatic ring. These compounds play a crucial role in various industries, including pharmaceuticals, fragrances, and specialty chemicals. Their unique properties and versatility make them valuable intermediates and building blocks for a wide range of products that are essential to the global economy.

Production process

The production of aromatic ketones under HS code 291439 typically involves a multi-step process. The first step is the synthesis of the aromatic ring structure, often through reactions such as Friedel-Crafts acylation or Grignard reactions. The resulting intermediate is then subjected to further functionalization, such as the introduction of the carbonyl group, to yield the desired aromatic ketone. The specific production techniques may vary depending on the target compound and the desired level of purity and yield.

Production inputs

The main inputs required for the production of aromatic ketones under HS code 291439 include aromatic hydrocarbons, such as benzene or toluene, as well as various reagents and catalysts necessary for the synthetic steps. Additionally, specialized equipment, such as reactors, distillation columns, and purification systems, are essential for the efficient and high-quality production of these compounds.

Production outputs

The aromatic ketones produced under HS code 291439 are widely used as intermediates in the synthesis of a variety of other chemicals and products. They may be consumed by industries such as 291500 Esters; acyclic, cyclic or heterocyclic, and their halogenated, sulphonated, nitrated or nitrosated derivatives, 293090 (Heterocyclic compounds with oxygen hetero-atom(s) only), and 293999 (Heterocyclic compounds with nitrogen hetero-atom(s) only, not elsewhere specified or included).
