Salicylic acid and its salts and esters

CPC v2.1 Code: 35210

About salicylic acid and its salts and esters

cpc code 35210 covers the production and trade of salicylic acid and its various salts and esters. Salicylic acid is a widely used chemical compound with a diverse range of applications, from pharmaceuticals and personal care products to industrial processes. As a key ingredient in many consumer goods, the salicylic acid industry plays a vital role in the broader chemical and manufacturing sectors, contributing to the global economy.

Production process

The primary production method for salicylic acid involves the reaction of phenol with carbon dioxide under high temperature and pressure conditions. This process, known as the Kolbe-Schmitt reaction, yields sodium salicylate, which is then converted to salicylic acid through acidification. Manufacturers may also utilize alternative synthesis routes, such as the oxidation of salicyl alcohol or the hydrolysis of methyl salicylate, depending on the specific requirements and production capabilities.

Production inputs

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

Production outputs

The primary output of cpc code 35210 is salicylic acid, which is then used as a raw material for the production of a wide range of products, including 35420 Medicinal and pharmaceutical products, 33740 Soaps, cleansing and polishing preparations, and 35290 Other organic chemical products. Salicylic acid and its salts and esters are also utilized in the manufacture of various agricultural chemicals, dyes, and other specialty chemicals.
