Salicylic acid and its salts and esters

CPC v2.1 Code: 3521

About salicylic acid and its salts and esters

cpc code 3521 covers the production and processing of salicylic acid and its various salts and esters. Salicylic acid is a widely used organic compound with a diverse range of applications, from pharmaceutical and cosmetic industries to the production of various chemical intermediates. This industry plays a crucial role in the global supply chain, providing essential inputs for a variety of downstream sectors.

Production process

The primary production technique for salicylic acid involves the reaction of phenol with carbon dioxide under high temperature and pressure conditions. The resulting salicylic acid is then further processed to produce various salts and esters, each with their own unique properties and applications.

Production inputs

The main inputs required for the production of salicylic acid and its derivatives include phenol, carbon dioxide, and various catalysts and solvents. Additionally, specialized equipment such as high-pressure reactors, distillation columns, and crystallization units are necessary for the efficient and large-scale production of these chemicals.

Production outputs

The primary outputs of this industry are salicylic acid, as well as its various salts and esters, such as sodium salicylate, methyl salicylate, and acetylsalicylic acid (aspirin). These products find widespread use in the 3053 Pharmaceutical preparations, 2023 Soap and detergents, cleaning and polishing preparations, and 2029 Other chemical products n.e.c. industries.
