About aldehydes; acyclic, without other oxygen function, n.e.c. in item no. 2912.1
HS code 291219 covers a diverse range of acyclic aldehydes that do not contain any other oxygen functions. These aldehydes are widely used as intermediates and building blocks in the production of various chemicals, pharmaceuticals, and other industrial products. They play a crucial role in the global chemical industry, contributing to the manufacturing of essential goods and enabling advancements across multiple sectors.
Production process
The production of aldehydes under HS code 291219 typically involves the oxidation of alcohols or the hydroformylation of alkenes. Oxidation processes, such as the use of chromium-based reagents or catalytic dehydrogenation, are commonly employed to convert alcohols into their corresponding aldehydes. Alternatively, the hydroformylation of alkenes, using carbon monoxide and hydrogen in the presence of a transition metal catalyst, can also yield acyclic aldehydes.
Production inputs
The main inputs required for the production of aldehydes under HS code 291219 include alcohols, alkenes, and various oxidizing agents or hydroformylation catalysts. Depending on the specific aldehyde being produced, the raw materials may include ethanol, propanol, butanol, or other higher alcohols, as well as ethylene, propylene, or other alkenes. Additionally, the production process may require the use of specialized equipment, such as reactors, distillation columns, and purification systems.
Production outputs
The aldehydes produced under HS code 291219 are widely used as intermediates in the synthesis of a wide range of chemicals, including 291531 Formaldehyde, 291532 Acetaldehyde, 291533 Butyraldehyde, and other higher acyclic aldehydes. These aldehydes are then further processed and incorporated into the production of various end-products, such as pharmaceuticals, fragrances, plastics, and agricultural chemicals, among others.
