Title (EN) PROCESS FOR PREPARING AMIDOALKANESULFONIC ACIDS AND THEIR DERIVATIVES
(FR) PROCEDE DE PREPARATION D"ACIDES AMIDOALCANESULFONIQUES ET DE LEURS DERIVES
Abstract:
(EN) A novel process for preparing amidoalkanesulfonic acids represented by formula (3) and their derivatives by reacting a nitrile compound (1) with beta-hydroxyalkanesulfonic acid or its derivative (2) in conc. sulfuric acid. Of the compounds of the formula (3) and their derivatives, unsaturated amidophenyl-substitued alkanesulfonic acids represented by formula (4) and their derivatives, particularly, 2-acrylamido-2-phenylpropanesulfonic acid and its derivatives are copolymerized with other monomers to provide useful materials such as copolymer-coated solid substances, copolymer emulsions, and pigment-dispersing agent.
(FR) Nouveau procédé de préparation d"acides amidoalcanesulfoniques représentés par la formule (3) et leurs dérivés, en faisant réagir un composé nitryl (1) avec un acide beta-hydroxyalcanesulfonique ou son dérivé (2) dans de l"acide sulfurique concentré. Des composés de la formule (3) et leurs dérivés, des acides alcanesulfoniques non saturés substitués par un amido phényl, représentés par la formule (4) et leurs dérivés, notamment l"acide 2-acrylamido-2-phénylpropanesulfonique et ses dérivés sont copolymérisés avec d"autres monomères afin d"obtenir des matériaux utiles tels que des substances solides recouvertes d"un copolymère, des émulsions copolymères et des agents de dispersion de pigment.
