Abstract

A catalyst for promoting the commercialization of N-phenylamleimide (PMI), a compound used to strengthen the heat resistance of ABS resins and also completely imported, was developed. N-phenylmaleamic acid (PMA) was first quantitatively obtained through the reaction of maleic anhydride and aniline. A catalyst was then investigated for obtaining PMI. Zinc acetate/$Et_3N$, composite catalyst, showed better performance than a single acid catalyst. By using the developed composite catalyst, PMI could be synthesized with the yield and purity of 90% and 99.3%, respectively without any further purification processes.

전량 수입에 의존하고 있는 ABS 수지의 내열성 강화를 위한 화합물인 N-phenylamleimide (PMI)의 상업화를 위한 촉매개발을 완료하였다. Maleic anhydride와 aniline과 반응을 통하여 중간체인 N-phenylmaleamic acid (PMA)를 정량적으로 얻은 후, PMI를 얻기 위한 촉매를 탐색하였다. Zinc acetate/$Et_3N$의 복합 촉매가 단일 산 촉매보다 우수한 성능을 보임을 확인하였다. 개발된 복합 촉매를 사용하여 추가 정제 공정 없이 90% 수율과 99.3%의 순도로 PMI를 합성할 수 있었다.
