Halogenated derivatives of hydrocarbons

HS v2022 Code: 2903

About halogenated derivatives of hydrocarbons

HS code 2903 covers a diverse range of halogenated derivatives of hydrocarbons, which are organic compounds containing one or more halogen atoms (such as chlorine, bromine, or fluorine) attached to a hydrocarbon backbone. These compounds play a crucial role in various industries, including pharmaceuticals, agrochemicals, and specialty chemicals, due to their unique properties and applications.

Production process

The production of halogenated derivatives of hydrocarbons typically involves a series of chemical reactions, such as halogenation, substitution, or addition, performed on the hydrocarbon precursors. The specific techniques used depend on the target compound and may include methods like electrophilic or nucleophilic halogenation, radical halogenation, or catalytic hydrohalogenation.

Production inputs

The main inputs required for the production of halogenated derivatives of hydrocarbons include hydrocarbon feedstocks (such as 2901 Acyclic hydrocarbons, 2902 Cyclic hydrocarbons, or 2905 Acyclic alcohols and their halogenated, sulfonated, nitrated or nitrosated derivatives), halogen sources (such as chlorine, bromine, or fluorine), and various catalysts and reagents depending on the specific reaction processes.

Production outputs

The halogenated derivatives of hydrocarbons produced under HS code 2903 have a wide range of applications and are consumed by various other industries. These compounds may be used as solvents, refrigerants, propellants, intermediates in the production of 2907 Phenols; phenol-alcohols, 2914 Ketones and quinones, whether or not with other oxygen function, and their halogenated, sulfonated, nitrated or nitrosated derivatives, and other specialty chemicals.
