HS v2017 Code: 291550

About acids; saturated acyclic monocarboxylic acids; propionic acid, its salts and esters

HS code 291550 covers a group of organic chemicals known as saturated acyclic monocarboxylic acids, with propionic acid being the primary focus. These acids play a crucial role in various industries, including food preservation, pharmaceutical manufacturing, and chemical synthesis. As a key component in the production of esters, salts, and other derivatives, propionic acid and its related compounds are essential building blocks for a wide range of products that are integral to the global economy.

Production process

Propionic acid and its salts and esters are typically produced through chemical synthesis. The most common method involves the oxidation of propionaldehyde, which is derived from the hydroformylation of ethylene. Alternatively, propionic acid can be obtained through the fermentation of carbohydrates, such as glucose or lactose, by certain bacteria. The resulting acid is then purified and processed into the desired salts or esters through additional chemical reactions.

Production inputs

The main inputs required for the production of propionic acid and its derivatives include propionaldehyde, ethylene, and various oxidizing agents, such as oxygen or hydrogen peroxide. Depending on the desired end product, additional raw materials like alcohols or bases may be needed for the synthesis of salts and esters. The production process also requires specialized equipment, such as reactors, distillation columns, and purification systems, to ensure the quality and consistency of the final products.

Production outputs

The primary output of HS code 291550 is propionic acid, which is then used to manufacture a variety of salts and esters. These derivatives find applications in 291550 acids; saturated acyclic monocarboxylic acids; propionic acid, its salts and esters, 291590 acids; saturated acyclic monocarboxylic acids, n.e.c. in heading no. 2915, and 292090 (esters of other inorganic acids (excluding esters of hydrogen halides) and their salts; and their halogenated, sulphonated, nitrated or nitrosated derivatives).
