Acids; acyclic polycarboxylic acids; oxalic acid, its salts and esters

HS v2017 Code: 291711

About acids; acyclic polycarboxylic acids; oxalic acid, its salts and esters

HS code 291711 covers a diverse range of acyclic polycarboxylic acids, including the important compound oxalic acid. These chemicals play a crucial role in various industries, from manufacturing to agriculture. As a key component in the production of many essential goods, the 291711 industry is a vital part of the broader chemical and materials sector, contributing significantly to the global economy.

Production process

The primary production method for acyclic polycarboxylic acids under HS code 291711 is chemical synthesis. This typically involves the oxidation of alcohols or the hydrolysis of esters to form the desired carboxylic acid compounds. Oxalic acid, in particular, is often produced by the oxidation of carbohydrates or the hydrolysis of oxalates. Advanced techniques, such as catalytic processes, may also be employed to optimize yield and efficiency.

Production inputs

The main inputs required for the 291711 industry include various organic feedstocks, such as alcohols, esters, and carbohydrates. Specialized equipment, such as reactors, distillation columns, and purification systems, are also essential for the chemical synthesis and refinement processes. Energy sources, such as electricity or steam, are necessary to power the production facilities.

Production outputs

The primary outputs of the 291711 industry are the acyclic polycarboxylic acids themselves, including oxalic acid and its salts and esters. These chemicals find widespread use in a variety of downstream industries, such as 291500 (Esters of other inorganic acids (excluding esters of hydrogen halides)) for the production of plasticizers, 283620 Calcium carbonate for use in construction materials, and 284190 Inorganic acids and inorganic oxygen compounds of non-metals, n.e.c. for various industrial and agricultural applications.
