N,N-DIALLYLAMINOETHANOIC ACID AND SYNTHESIS METHOD THEREOF Russian patent published in 2012 - IPC C07C227/18 C07C229/30 

FIELD: chemistry.

SUBSTANCE: invention relates to a novel method of producing N,N-diallylaminoethanoic acid which is used in synthesis of water-soluble polyelectrolytes. The method involves reaction of allyl chloride with a reaction mixture cooled to 0-5°C consisting of α-aminoacetic acid and sodium hydroxide in a water-alcohol solution for 15-30 minutes. Further, the reaction temperature is raised to 60-75°C and the reaction mixture is held for 3-5 hours. After the reaction, the reaction mixture gradually poured into dry acetone in portions. N,N-diallylaminoethanoic acid in form of flakes gathers on the surface of acetone and salts precipitate.

EFFECT: novel method of producing N,N-diallylaminoethanoic acid.
