Synthesis of N-phenylmaleimide Catalyzed by Cyanuric Chloride
In this paper,the synthesis process of N-phenylmaleimide(N-PMI)was innovated.N-phenylmaleamide acid(N-PMA)was synthesized from maleic anhydride and aniline in ethyl acetate,toluene and chlorobenzene,respectively;Then N-PMI was prepared in different solvents with cyanuric chloride and triethylamine as catalysts.The improved process is relatively simple and the required raw materials and reagents are easily available,which provides a new idea for the synthesis of N-PMI.
