bentseenisulfonaatti

Bentseenisulfonaatti is the anion or salt derived from benzenesulfonic acid. Benzenesulfonic acid is an organosulfur compound with the formula C6H5SO3H. When it loses a proton, the resulting benzenesulfonate anion, C6H5SO3-, is formed. Salts of benzenesulfonic acid contain this anion paired with a cation, such as sodium benzenesulfonate (C6H5SO3Na) or potassium benzenesulfonate (C6H5SO3K). These salts are often crystalline solids and are generally soluble in water.

Benzenesulfonic acid itself is a strong acid and is used as a catalyst in various organic reactions, including alkylation and acylation. The benzenesulfonate anion is a relatively stable and weakly basic anion. It is a common counterion found in pharmaceuticals and other chemical compounds. For example, certain drugs are administered as their benzenesulfonate salts to improve solubility or stability. The production of benzenesulfonic acid and its derivatives typically involves the sulfonation of benzene using sulfuric acid or sulfur trioxide. These compounds play a role in the synthesis of dyes, detergents, and other industrial chemicals.
