Klorosulfonihapon

Klorosulfonihapon, also known as chlorosulfonic acid, is a colorless, fuming liquid with the chemical formula HSO₃Cl. It is a highly corrosive and reactive inorganic compound. Klorosulfonihapon is a strong acid and a powerful sulfonating and chlorinating agent. It reacts violently with water, producing sulfuric acid and hydrochloric acid, releasing significant heat and corrosive fumes. Due to its reactivity, it must be handled with extreme caution in well-ventilated areas and with appropriate personal protective equipment.

Klorosulfonihapon is primarily used in the chemical industry for various synthetic purposes. Its main application is in the production of detergents, specifically alkylbenzenesulfonates, which are key components in many cleaning products. It is also employed in the synthesis of sulfonamides, which are a class of drugs, and in the production of dyes and pigments. Additionally, it can be used as a sulfonating agent in organic chemistry to introduce the sulfonic acid group (-SO₃H) into organic molecules. Its dual nature as both a sulfonating and chlorinating agent makes it a versatile reagent in chemical synthesis, though its hazardous properties necessitate strict safety protocols during its use and storage.
