klorosulfonat

Klorosulfonat is a chemical compound with the formula ClSO2OH. It is also known by several other names, including chlorosulfonic acid and chlorosulfuric acid. This highly corrosive and reactive substance is a colorless liquid with a pungent odor. It is a strong acid and a powerful oxidizing agent.

Klorosulfonat is typically prepared by the reaction of sulfur trioxide with hydrogen chloride gas. It is an important reagent in organic chemistry, particularly for the sulfonation of aromatic compounds. This process introduces a sulfonic acid group (-SO3H) onto an aromatic ring, a crucial step in the synthesis of many dyes, pharmaceuticals, and detergents. Klorosulfonat can also be used to produce sulfonyl chlorides, which are intermediates in the synthesis of sulfonamides, a class of antibacterial drugs.

The reactivity of klorosulfonat means it must be handled with extreme caution. It reacts violently with water, producing sulfuric acid and hydrogen chloride, both of which are corrosive. It can also react with many organic compounds, sometimes explosively. Due to its hazardous nature, its use is typically confined to industrial settings with strict safety protocols. Storage requires specialized containers that are resistant to corrosion and moisture.
