- 제2항에 있어서, 상기 폐환 이미드화 반응이 안정제 및 아연, 크롬, 코발트, 니켈, 철, 알루미늄 및 팔라듐으로 구성된 군으로부터 선택되는 하나 이상의 금속을 함유하는 화합물의 존재하에 진행되는 방법.
- 제4항에 있어서, 상기 산촉매가 황산, 황산 무수물, p-톨루엔술폰산, 오르토인산, 메타인산 및 피로인산으로 구성된 군으로부터 선택되는 하나이상의 산인 방법.
- 제6항에 있어서, 상기 금속을 함유한 화합물이 아연함유 화합물인 방법.
- 제8항에 있어서, 상기 아연함유 화합물이 아연아세테이트인 방법.
- 제6항에 있어서, 상기 안정제가 퀴는류, 페놀류, 티오-프로피온산 에스테르, 디티오카르바메이트, 살리실레이트, 알킬화디페닐아민, 페노티아진, 메르캅토이미다졸 및 트리페닐포스페이트류로 구성된 군으로부터 선택되는 하나이상의 화합물인 방법.
- 제1항에 있어서, 상기 유기용매층으로부터 회수된 산촉 매층이 상기 폐환이미드화 반응 단계에 순환되기 이전에 거기에 5-20중량%의 물을 가하는 방법.※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
