Abstract

본 발명은 피닐피롤리돈의 제조방법에 관한 것으로서, 더욱 상세하게는 피롤리돈에 알카리금속수산화물 촉매 및 아세틸렌을 부가시켜 비닐피롤리돈 제조시 조촉매로서 다음 구조식(I) 또는 구조식(II)로 표시되는 에틸렌아민 유도체를 첨가하여 반응생성물 중에 부생성물로 존재하는 비휘발성 고분자 잔분을 획기적으로 감소시켜 비닐피롤리돈의 수율을 향상시킴은 물론 비닐피롤리돈의 분리 및 정제를 손쉽게 해결할 수 있는 비닐피롤리돈의 신규한 제조방법에 관한 것이다.
상기식에서, R은 수소원자 또는 C1~C2의 알킬기이고, R1는 C1~C2의 알킬기 또는 -C(O)-R2이고, 이때 R2는 C1~C2의 알킬기이며, n은 1 내지 4의 정수이다.
