HS v2017 Code: 291521

About acids; saturated acyclic monocarboxylic acids; acetic acid

HS code 291521 covers the classification of saturated acyclic monocarboxylic acids, with a specific focus on acetic acid. These organic compounds are widely used in various industries, playing a crucial role in the production of a diverse range of products. Acetic acid, in particular, is a key ingredient in the manufacture of 320110 Acetic acid, 291521 Vinyl acetate, and numerous other chemical intermediates, making it an essential component of the global chemical supply chain.

Production process

The primary production technique for acetic acid is the carbonylation of methanol. This process involves the reaction of methanol with carbon monoxide in the presence of a catalyst, typically rhodium or iridium, to form acetic acid. The reaction is carried out under high temperature and pressure conditions, ensuring optimal conversion rates and product yields. Alternatively, acetic acid can also be produced through the oxidation of acetaldehyde or the fermentation of biomass, such as agricultural waste or byproducts.

Production inputs

The main inputs required for the production of acetic acid and other saturated acyclic monocarboxylic acids include methanol, carbon monoxide, and various catalysts. Additionally, the production process may require specialized equipment, such as high-pressure reactors, distillation columns, and purification systems, to ensure the quality and purity of the final product. Energy sources, such as electricity or steam, are also essential for powering the production facilities and maintaining the necessary process conditions.

Production outputs

The primary output of HS code 291521 is acetic acid, which is widely used as a chemical intermediate in the production of a variety of products, including 320110 Acetic acid, 291521 Vinyl acetate, and 291531 Ethyl acetate. Acetic acid is also used in the manufacture of various pharmaceuticals, food additives, and household products. Additionally, other saturated acyclic monocarboxylic acids classified under this code may find applications in the production of lubricants, plasticizers, and other specialty chemicals.
