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

HS v2022 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 widely used in the production of various pharmaceutical and chemical products, playing a crucial role in the global pharmaceutical and fine chemicals industries. As a key intermediate, the demand for phenylacetone is closely tied to the performance and growth of these important economic sectors.

Production process

Phenylacetone is typically produced through the catalytic oxidation of ethylbenzene. This process involves the reaction of ethylbenzene with oxygen in the presence of a suitable catalyst, such as cobalt or manganese compounds. The resulting phenylacetone is then purified and prepared for further downstream processing or direct use in various applications.

Production inputs

The main inputs required for the production of phenylacetone include ethylbenzene as the primary raw material, as well as catalysts, solvents, and energy sources to facilitate the oxidation reaction. Specialized equipment, such as reactors, distillation columns, and purification systems, are also essential for the efficient and high-quality production of this aromatic ketone.

Production outputs

The primary output of HS code 291431 is phenylacetone, which is a versatile intermediate used in the synthesis of various pharmaceutical and fine chemical products. This includes the production of 294110 amphetamine, 294120 methamphetamine, and other stimulant drugs, as well as the manufacture of certain perfumes and fragrances.
