Abstract

본 발명은 산, 염기 촉매 존재하에서 메타크릴산과 산화에틸렌을 부가반응시켜 얻어진 2-하이드록시 에틸 메타아크레이트를 정제하는 방법에 관한 것으로서, 유기용제로 에틸렌 디클로라이드, 메틸렌 디클로라이드와 같은 할로탄화수소 또는 톨루엔과 같은 방향족 탄화수소를 사용하는 용매추출법으로 정제함을 특징으로 한다.The present invention relates to a method for purifying 2-hydroxy ethyl methacrylate obtained by addition reaction of methacrylic acid and ethylene oxide in the presence of an acid or a base catalyst, wherein the organic solvent is a halohydrocarbon such as ethylene dichloride, methylene dichloride or It is characterized in that the purification by the solvent extraction method using an aromatic hydrocarbon such as toluene.

본 발명에 따르면 증류도중에 중합이 일어날 가능성이 없고, 잔유물이 생성되지 않아 제거 공정이 필요없고, 미반응 메타아크릴산과 부산물이 수용액층으로 충분히 제거되어 고순도의 제품을 고수율로 얻을 수 있다.According to the present invention, there is no possibility of polymerization during distillation, no residues are generated, and no removal process is required, and unreacted methacrylic acid and by-products are sufficiently removed in the aqueous solution layer to obtain a high-purity product in high yield.
