Polyphenols; resorcinol and its salts

HS code 290721 covers polyphenols, resorcinol, and its salts. These organic compounds are widely used in the production of various industrial and consumer goods, playing a crucial role in the global chemical industry. Polyphenols, in particular, are valued for their antioxidant properties and are found in a variety of natural sources, such as plants, fruits, and vegetables. Resorcinol and its salts have diverse applications, from the manufacture of resins and dyes to the production of pharmaceuticals and personal care products. Understanding the importance and production processes of these chemical compounds is essential for businesses involved in the import, export, and trade of these materials.

The production of polyphenols, resorcinol, and its salts typically involves a series of chemical reactions and purification processes. Polyphenols are often extracted from natural sources, such as plant materials, through processes like solvent extraction or supercritical fluid extraction. Resorcinol, on the other hand, is commonly produced through the sulfonation of benzene, followed by hydrolysis and purification steps. The specific production techniques may vary depending on the desired purity, properties, and end-use applications of the final products.

The main inputs required for the production of polyphenols, resorcinol, and its salts include raw materials such as benzene, phenol, and other aromatic compounds. Additionally, various solvents, catalysts, and reagents are used in the chemical synthesis and purification processes. Specialized equipment, such as reactors, distillation columns, and filtration systems, are also essential for the efficient and high-quality production of these chemical compounds.

The outputs of HS code 290721 include a wide range of polyphenols, resorcinol, and its salts, which are then used as intermediates or raw materials in the production of various downstream products. These outputs may be consumed by industries such as 290700 Phenols; phenol-alcohols for the manufacture of resins, dyes, and pharmaceuticals, 320100 Tanning extracts of vegetable origin; tannins and their salts, ethers, esters and other derivatives for the production of tanning agents, and 382490 Chemical products and preparations of the chemical or allied industries, not elsewhere specified or included for the formulation of personal care and household products.
