Vinylsulfonic

Vinylsulfonic acid is an organic compound with the chemical formula CH2=CHSO3H. It is a vinyl group attached to a sulfonic acid group. Vinylsulfonic acid is a strong acid and is highly reactive due to the presence of both the vinyl group and the sulfonic acid functional group. It can undergo polymerization reactions, forming poly(vinylsulfonic acid). This polymer finds applications as a flocculant, a dispersant, and a component in ion-exchange resins and membranes. The monomer itself is also used in the synthesis of various specialty chemicals and polymers. Due to its acidic and reactive nature, vinylsulfonic acid is typically handled with care and often stored in stabilized forms or as its salts. It can be synthesized through various methods, including the oxidation of vinyl mercaptan or the reaction of ethylene with sulfur trioxide followed by hydrolysis. Its properties make it a valuable intermediate in chemical manufacturing, particularly for applications requiring water solubility and ionic character.
