Abstract

본 발명은 아크릴산 알킬에스테르를 3급 아미노 알코올과 반응시켜 교환에스테르(Transesterification) 아크릴산 아미노알킬에스테르 화합물로 제조하는데 있어서, 새로운 반응용매를 사용하여 출발물질인 아크릴산 알킬에스테르의 사용량을 최소한으로 줄이고, 중합 부반응을 억제시킨 아크릴산 아미노알킬에스테르의 새로운 제조방법에 관한 것이다.In the present invention, the acrylic ester of acrylic acid is reacted with a tertiary amino alcohol to prepare a transesterification amino alkyl ester compound, using a new reaction solvent to minimize the amount of the alkyl acrylate ester, which is a starting material, and to minimize the polymerization side reaction. It relates to a new method for producing acrylic acid aminoalkyl esters.
