Process for preparing amidoalkanesulfonic acids
-
, (2008/06/13)
Disclosed is a novel process for preparing amidoalkanesulfonic acids of the general formula STR1 or derivatives thereof by reacting a nitrile compound (1) with a β-hydroxyalkanesulfonic acid or a derivative thereof (2) in concentrated sulfuric acid. Among the compounds of the general formula (3) and derivatives thereof, unsaturated amido- and phenyl-substituted alkanesulfonic acids and derivatives thereof (in particular, 2-acrylamido-2-phenylpropane-sulfonic acid and derivatives thereof) represented by the general formula STR2 can be copolymerized with other monomers and the like to provide useful materials such as copolymer-coated solid materials, copolymer emulsions, pigment dispersants and the like.
