Abstract
FIELD: organic chemistry. SUBSTANCE: product: 2-[3-(N,N,N-trialkylammonio)propionamido] -2-methylpropanesulfo- nates of the general formulawhere. Method involves interaction of tertiary amines with 2-acrylamido-2-methylpropanesulfoacid in an aqueous medium followed by isolation of the end product by solvent and unreacted parental substances removal. Process is carried out at mole ratio of tertiary amine and 2-acrylamido-2-methylpropanesulfoacid = (1.02-2.10):1.00. EFFECT: improved method of synthesis.

Изобретение относится к органической химии, в частности к способам получения 2-[3-(N, N,N-триалкиламмонио)- пропионанидо]-2-метилпропансульфонатов общей формулы, приведенной в описании. Способ включает взаимодействие третичных аминов с 2-акриламидо2-метилпропансульфокислотой в водной среде с последующим выделением целевого продукта путем удаления растворителя и непрореагировавших исходных веществ. Процесс осуществляют при мольном соотношении третичного амина и 2-акриламидо-2-метилпропансульфокислоты, равном (1,02 - 2,10) : 1,00.The invention relates to organic chemistry, in particular to methods for producing 2- [3- (N, N, N-trialkylammonio) propionanido] -2-methylpropanesulfonates of the general formula given in the description. The method involves the interaction of tertiary amines with 2-acrylamido-2-methylpropanesulfonic acid in an aqueous medium, followed by isolation of the target product by removing the solvent and unreacted starting materials. The process is carried out at a molar ratio of tertiary amine and 2-acrylamido-2-methylpropanesulfonic acid equal to (1.02 - 2.10): 1.00.
