Acids; aromatic monocarboxylic acids, benzoic acid, its salts and esters

HS v2022 Code: 291631

About acids; aromatic monocarboxylic acids, benzoic acid, its salts and esters

HS code 291631 covers a group of aromatic monocarboxylic acids, including the widely used benzoic acid and its various salts and esters. These compounds play a crucial role in a diverse range of industries, from food preservation and personal care products to pharmaceuticals and plastics. As a key component in the production of many essential goods, this industry is a vital part of the broader chemical and manufacturing sectors.

Production process

The primary production method for benzoic acid and related compounds involves the oxidation of toluene, a common aromatic hydrocarbon. This process typically uses a catalytic reaction with oxygen or other oxidizing agents to convert the toluene into benzoic acid. Manufacturers may also employ other techniques, such as the hydrolysis of benzyl chloride or the carbonation of benzene, depending on the specific compound being produced.

Production inputs

The main inputs for this industry include toluene, as well as other aromatic hydrocarbons, oxidizing agents, and various catalysts. Manufacturers also require specialized equipment, such as reactors, distillation columns, and purification systems, to efficiently produce and refine the desired compounds. Energy sources, such as electricity or steam, are also essential for powering the production processes.

Production outputs

The primary outputs of this industry are benzoic acid and its various salts and esters, which find applications in a wide range of industries. Benzoic acid is commonly used as a food preservative 210120 Food Preservatives, while its salts and esters are utilized in personal care products, pharmaceuticals, and the production of other chemicals, such as 291532 Benzoyl Peroxide and 291733 Benzoic Acid Esters.
