Imides and their derivatives; saccharin and its salts
HS v2022 Code: 292511
About imides and their derivatives; saccharin and its salts
HS code 292511 covers the production and trade of imides and their derivatives, as well as saccharin and its salts. Imides are a class of organic compounds with a wide range of applications, from pharmaceuticals to agricultural chemicals. Saccharin, on the other hand, is an artificial sweetener used in various food and beverage products. This industry plays a crucial role in the global chemical and food industries, providing essential inputs for a diverse range of downstream applications.
Production process
The production of imides and their derivatives, as well as saccharin, typically involves a multi-step chemical synthesis process. Key steps may include the reaction of amines with cyclic anhydrides to form imides, as well as the oxidation and sulfonation of toluene to produce saccharin. Advanced techniques, such as continuous flow chemistry and biocatalysis, are increasingly being adopted to improve efficiency and sustainability.
Production inputs
The main inputs required for this industry include a range of organic chemicals, such as amines, anhydrides, and toluene. Additionally, specialized equipment, such as reactors, distillation columns, and purification systems, are necessary for the production of these compounds. Energy, water, and skilled labor are also important inputs for this industry.
Production outputs
The outputs of this industry include a variety of imides and their derivatives, as well as saccharin and its salts. These products are then consumed by a wide range of industries, including 300000 Pharmaceutical products, 310000 Fertilizers, and 220000 Beverages, spirits and vinegar. The imides and their derivatives may also be used in the production of 292700 Sulfonamides, 292400 (Heterocyclic compounds with nitrogen hetero-atom(s) only), and other specialty chemicals.
