Amine-function compounds; aromatic monoamines and their derivatives, aniline and its salts

HS v2017 Code: 292141

About amine-function compounds; aromatic monoamines and their derivatives, aniline and its salts

HS code 292141 covers a diverse range of aromatic monoamines and their derivatives, including the important chemical compound aniline. These amine-function compounds are essential building blocks for a wide variety of products, from pharmaceuticals and dyes to pesticides and plastics. As a key component in many industrial processes, this code plays a vital role in the global chemical industry and broader manufacturing sectors.

Production process

The primary production method for HS code 292141 compounds involves the catalytic hydrogenation of nitro-aromatic compounds. This process typically uses metal catalysts, such as nickel or platinum, to selectively reduce the nitro group (-NO2) to an amino group (-NH2), forming the desired amine-function compound. Careful control of reaction conditions, including temperature, pressure, and catalyst selection, is crucial to optimize yield and product purity.

Production inputs

The main inputs required for the production of HS code 292141 compounds include aromatic nitro compounds, such as nitrobenzene, as well as hydrogen gas, catalysts, and various solvents and reagents. Specialized production equipment, such as hydrogenation reactors, distillation columns, and purification systems, are also essential for the efficient and high-quality manufacture of these chemicals.

Production outputs

The amine-function compounds classified under HS code 292141 are widely used as intermediates in the production of a diverse range of downstream products. These include 292142 Aniline and its salts, 292143 Toluidines and their derivatives; salts thereof, and 292144 Diphenylamine and its derivatives; salts thereof, which are further processed into pharmaceuticals, dyes, pesticides, and other specialty chemicals. The outputs of this industry are crucial inputs for many other 29 Organic chemicals and 30 Pharmaceutical products classifications.
