HS v2022 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 fundamental building block for numerous chemical processes and is a key component in the manufacture of various 320611 paints and varnishes, 291521 vinegar, and 292150 pharmaceutical products.
Production process
The production of saturated acyclic monocarboxylic acids, including acetic acid, typically involves the oxidation of alcohols or the hydrolysis of esters. In the case of acetic acid, the most common production method is the carbonylation of methanol, where carbon monoxide and methanol are combined to form acetic acid. This process is often carried out using a catalyst, such as rhodium or iridium, to improve efficiency and yield.
Production inputs
The main inputs required for the production of saturated acyclic monocarboxylic acids, such as acetic acid, include alcohols, esters, and various catalysts. Depending on the specific production method, other raw materials like carbon monoxide may also be necessary. Additionally, the industry relies on specialized equipment and machinery, such as reactors, distillation columns, and purification systems, to ensure the efficient and high-quality production of these organic compounds.
Production outputs
The primary output of HS code 291521 is acetic acid, which is widely used in the production of 291521 vinegar, 291521 food preservatives, 291521 pharmaceutical intermediates, and 320611 paints and coatings. Other saturated acyclic monocarboxylic acids classified under this code may also find applications in various industries, such as the production of 291521 plasticizers, 291521 lubricants, and 291521 textile chemicals.
