摘　　要：以苯酐和正丁胺为原料,以水为溶剂,以三乙胺为催化剂,合成了N-丁基邻苯二甲酰亚胺,探索了催化剂的用量、物料配比、反应时间、反应温度等因素产品收率的影响,从而找出了制备N-丁基邻苯二甲酰亚胺的最佳工艺条件:苯酐与正丁胺的摩尔比1:1.3,催化剂三乙胺的为苯酐质量的百分数为16%,反应时间2h,收率达到97%。The synthesis of N-butylphthalimide from the reaction of o-phthalic anhydride and 1-aminohutane was carried out in catalyst triethylamine and used water as solvent. The effect of material ratio, the amount of catalyst, reaction time and reaction temperature on product yield was studied. The optimum conditions to the preparation of N-butylphthalimide was found with the moler ratio o-phthalic and n-butylamine 1 ： 1.3, the mass fraction of the catalyst triethylamine 2.5 g, reaction time 2 h. The yield of N-butylphthalimide was 98%.
