摘要： A novel process for preparing amidoalkanesulfonic acids represented by formula (3) and their derivatives by reacting a nitrile compound (1) with p-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.

摘要： Hydroxyalkanesulfonic acids represented by the general formula I, (wherein R represents a lower alkyl group containing 1 to 10 carbon atoms) and their derivatives such as alkali metal salts thereof are novel compounds prepared by, for example, reacting a-alkylstyrene with hydrogensulfite ion in an aqueous medium in the presence of oxygen. They are useful as starting materials for producing amidoalkanesulfonic acid derivatives for use as dispersing agents for lime soap, water-soluble high-molecular materials, and fiber- modifying materials.

摘要： 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.

摘要： Novel compounds represented by the formula:
wherein R 1 represent an aliphatic hydrocarbyl group, an aromatic hydrocarbyl group or an alicyclic hydrocarbyl group, X represents hydrogen, a glycidoxy group or an N,N-diglycidylamino group, R 2 represents hydrogen or a methyl group, R 3 represents an alkyl group, an alkemyl group, or an aryl group, p represents 0 or 1, q represents an integer of 1 to 4; r represents 1 or 2, and s represents an integer of 1 to 4, are obtained by reacting an amide compound with a halide compound such as epihalohydrin or dihalopropanol in the presence of a strongly basic compound. They are useful as starting meterials for reactive diluents, cross-linking agents, etc.
