    • 본 발명은 N-치환 말레이미드류의 제조방법에 관한 것으로서, 더욱 상세하게는 기존 N-치환 말레인 아미드산을 제조 후 N-치환 말레이미드류를 제조하는 방법과 달리 N-치환 말레인 아미드산을 별도로 제조하지 않고, 유기용매, 산 촉매, 촉매 고정체, 탈수 조촉매와 안정화제를 투입한 후, 1차 아민을 투입하여 아민염화하고, 무수말레산을 투입하여 탈수 폐환 반응시켜 고순도와 고수율의 N-치환 말레이미드류를 제조하는 방법에 관한 것이다.
      본 발명에 따른 N-치환 말레이미드 제조방법은 고분자성 글리콜류를 촉매 고정체를 사용하여 촉매의 반응성을 향상시키고, 중합체의 생성을 억제시켜 종래의 제조방법에 비하여 더 높은 수율과 순도를 줄 수 있음을 확인하였다. 또한 촉매의 재사용을 위한 촉매층의 분리가 효과적으로 이루어지며 무수말레산의 적절한 추가로 보다 높은 수율을 제공하였다.
