以顺丁烯二酸酐和苯胺为原料,丙酮作溶剂,乙酸酐为脱水剂,三乙胺、醋酸钠为催化剂,加入自制阻聚剂,并用正交实验法优化合成工艺条件,合成N-苯基马来酰亚胺。产品收率可达93%,纯度99.5%以上。同时简单的考察了阻聚剂的用量对N-PMI收率的影响。 Using maleic anhydride and aniline as raw materials, acetone as solvent, acetic anhydride as dehydrating agent, triethylamine and sodium acetate as catalyst, adding self-made polymerization inhibitor and optimizing the synthesis conditions by orthogonal experiment to synthesize N-benzene Maleimide. Product yield up to 93%, purity of more than 99.5%. At the same time, the effect of polymerization inhibitor on the yield of N-PMI was simply investigated.
