Abstract

본 발명은 아크릴산 알킬에스테르를 3급 아미노 알코올과 교환에스테르(Transesterification) 반응시켜 아크릴산 아미노 알킬에스테르 화합물을 제조하는데 있어서, 종래의 단일 촉매를 새로운 2성분 촉매 조합방법으로 대체하여 반응시간을 단축하고 부반응물의 생성을 억제시킨 아크릴산 아미노알킬 에스테르의 신규한 제조방법에 관한 것이다.The present invention is to prepare an acrylic acid alkyl alkyl compound by transesterification reaction of an alkyl acrylate ester with a tertiary amino alcohol, replacing the conventional single catalyst with a new two-component catalyst combination method to shorten the reaction time and react side reactions. It relates to a novel process for producing acrylic acid aminoalkyl esters with suppressed production of
