摘要:Hydroxyalkanesulfonic acids of the general formula ##STR1## where R is a lower alkyl group having 1 to 10 carbon atoms, and derivatives (such as alkali metal salts and the like) of the sulfonic acids are novel compounds. These compounds can be prepared, for example, by a process which comprises reacting an α-alkylstyrene with the hydrogensulfite ion in an aqueous medium in the presence of oxygen. These compounds are useful as raw materials for the manufacture of amidoalkanesulfonic acid derivatives having such applications as lime soap dispersants, raw materials for the synthesis of water-soluble polymers, fiber modifiers and the like.
