Chlorosulphuric acid

HS code 280620 covers chlorosulphuric acid, a highly corrosive and reactive chemical compound. This substance plays a crucial role in various industrial processes, particularly in the production of other chemicals and pharmaceuticals. As a key intermediate, chlorosulphuric acid is an important component in the broader chemical industry, contributing to the manufacture of a wide range of products that are essential for modern society.

Chlorosulphuric acid is typically produced through the reaction of sulfur trioxide (SO3) with chlorine gas (Cl2). This process involves the controlled introduction of chlorine into a stream of sulfur trioxide, resulting in the formation of chlorosulphuric acid. The reaction is carefully monitored and controlled to ensure the desired purity and yield of the final product.

The primary inputs required for the production of chlorosulphuric acid are sulfur trioxide and chlorine gas. Sulfur trioxide is often generated on-site through the oxidation of sulfur dioxide, while chlorine gas is typically sourced from dedicated chlor-alkali production facilities. Additionally, the process may require specialized equipment, such as reaction vessels, distillation columns, and storage tanks, to facilitate the efficient and safe production of chlorosulphuric acid.

Chlorosulphuric acid is a versatile chemical that finds application in various industries. It is commonly used as an intermediate in the production of other chemicals, such as 280510 Sulphuric acid and 290531 Sulphonic acids. Additionally, chlorosulphuric acid may be consumed in the manufacture of certain pharmaceuticals and agrochemicals, where it serves as a key precursor or reagent.
