N-对位取代苯基马来酰亚胺系列化合物的合成

Study on synthesis of N-P-substituted phenyl maleimides

以对位取代苯胺化合物、马来酸酐和乙酸酐为主要原料，三乙胺作催化剂，同时加入金属盐阻聚剂，采用２步法合成了４种Ｎ－对位取代苯基马来酰亚胺化合物，使Ｎ－对位取代苯基马来酰亚胺的产率都达到８５％以上，纯度都提高到９９．５％以上。对４种Ｎ－对位取代苯基马来酰亚胺的结构和物性也作了表征。

Four N-P-substituted phenyl maleimides were synthesized with P-substituted aniline, maleic anhydride and acetic anhydride as primary materials, triethylamine as catalyst and metallic salt as polymerization retarder by two-step method. The yields of four N-P-substituted phenyl maleimides reached 85% and their purity was increased to over 99.5%. The structures and properties of four products were also characterized.
