Abstract

Using the maleic anhydride and aniline steam as raw materials,acetic anhydride as dehydrating agent,triethylamine and nickel acetic as catalyst,N-phenylmaleimiede has been synthesized.The results show that the best ratio is nmaleic anhydride:naniline =1.05～1.1:1,nacetic anhydride:naniline = 2.1:1,ntriethylamine:nnickel acetic:naniline = 1.08:0.25:1,and the final productive efficiency is 89%.And also,it has been analyzed by FT-IR and 1H NMR.
