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.
