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

HS v2017 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 are widely used in the production of various chemicals, pharmaceuticals, and other industrial applications. They play a crucial role in the global chemical industry, contributing to the development of a wide range of products that are essential for modern life.

Production process

The production of aromatic ketones covered under HS code 291439 typically involves a series of chemical reactions. The most common method is the Friedel-Crafts acylation, where an acyl chloride or anhydride is reacted with an aromatic compound in the presence of a Lewis acid catalyst, such as aluminum chloride. This process allows for the introduction of the carbonyl group onto the aromatic ring. Other techniques, such as oxidation of alcohols or the use of Grignard reagents, may also be employed depending on the specific aromatic ketone being produced.

Production inputs

The main inputs required for the production of aromatic ketones under HS code 291439 include aromatic compounds (such as benzene, toluene, or xylene), acyl chlorides or anhydrides, and various catalysts and solvents. Additionally, specialized equipment, such as reactors, distillation columns, and purification systems, are necessary for the efficient and safe production of these chemicals.

Production outputs

The aromatic ketones produced under HS code 291439 are used as intermediates in the synthesis of a wide range of chemicals, including pharmaceuticals, fragrances, and other specialty chemicals. Some of the common outputs and their related HS codes include 293624 Ketones, cyclanic, cyclenic or cycloterpenic, without other oxygen function, 293712 Ketones, aromatic, with other oxygen function, and 293719 Ketones, aromatic, without other oxygen function, n.e.c. in heading 2937.
