Ketones; aromatic, (without other oxygen function), phenylacetone (phenylpropan-2-one)

HS v2017 Code: 291431

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

HS code 291431 covers the classification of aromatic ketones, specifically phenylacetone (also known as phenylpropan-2-one). These compounds are important intermediates in the production of various pharmaceuticals, fragrances, and other specialty chemicals. The global market for aromatic ketones is driven by the growing demand for these versatile compounds across a range of industries, including the 30 Pharmaceutical and 33 Perfume and Cosmetic sectors.

Production process

Aromatic ketones like phenylacetone are typically produced through the oxidation of aromatic hydrocarbons. The most common method involves the catalytic oxidation of alkylbenzenes, such as toluene or ethylbenzene, using oxygen or other oxidizing agents. The reaction is often carried out in the presence of a metal catalyst, such as cobalt or manganese, to improve the efficiency and selectivity of the process.

Production inputs

The main inputs required for the production of aromatic ketones include the aromatic hydrocarbon feedstock (e.g., toluene or ethylbenzene), oxidizing agents, and catalysts. Additionally, the process may require solvents, energy sources, and various auxiliary materials depending on the specific production setup and scale.

Production outputs

The primary output of HS code 291431 is phenylacetone, which is a versatile intermediate used in the synthesis of various pharmaceuticals, fragrances, and other specialty chemicals. Phenylacetone may be further processed or converted into other 29 Organic Chemicals under different HS codes, such as 293924 (Heterocyclic compounds with nitrogen hetero-atom(s) only: Compounds containing an unfused pyridine ring (whether or not hydrogenated) in the structure) and 293999 (Heterocyclic compounds with nitrogen hetero-atom(s) only: Other).
