Abstract

본 발명은, 정류에 의해 분리시킬 (메타)아크릴산을 포함하는 출발 혼합물을 정류 칼럼에 직접 공급하지 않고, 먼저 정류 칼럼의 정류 영역의 중기측과 연결되는 가열식 체류 용기안으로 옮긴 후, 용기내에서 출발 혼합물을 비점으로 유지시키고, 상기의 출발 혼합물 대신에, 체류 용기의 바닥액체를 정류 칼럼으로 공급하는 것을 특징으로 하는, 스트립핑 영역 및 정류 영역으로 구성된 정류 칼럼내에서 (메트)아크릴산을 주성분으로 함유하고 저급알데히드를 2차 성분으로 함유하는 혼합물을 정류시켜 (메트)아크릴산을 단리시키는 방법에 관한 것이다.
