摘要
以顺丁烯二酸酐和苯胺为原料,用甲苯作共沸溶剂,自制固体超强酸作催化剂,加入阻聚剂,合成的N_苯基马来酰亚胺的收率97%,纯度99%以上。在此基础上进行中试试验,可获得相同收率纯度的产品。
N-phenyl maleimide was synthesized from maleic anhydride and aniline with toluene as azeotropic solvent, self-made solid ultra strong acid as catalyst, adding retarder. The results show that the yield may reach 97%; the purity is above 99%.The pilot scale experiment can achieve the same result on this basis.
