摘　　要：以间－甲酚为原料，经硝化，甲基化，还原，缩合等反应合成了４－甲氧基－２－甲基－Ｎ－苯基苯胺；并以间－二乙氨基苯酚为原料，与苯酐通过Ｆｒｉｅｄｅｌ－Ｃｒａｆｔｓ反应，合成了２－羧基－４′－二乙氨基－２′－羟基二苯甲酮。在此基础上，合成了２－苯基－氨基－３－甲基－６－二乙氨基荧烷（ＯＤＢ）等一系列荧烷系染料。所有结构都经过元素分析和′ＨＮＭＲ等谱图验证结构正确。With raw material 3methyl phenol,4methoxy2methylNphenyl benzenamine was synthesized through nitrationmethylationreduction and condensation.From N,Ndiethylmaminophenol,4N,Ndiethylamino2hydroxy2carboxybenzophenone was synthesized through FriedelCrafts reaction.On the basis of these intermediates,a series of fluorane dyes were synthesized,and they were characterized by elemental analysis and HNMR spectroscopy.\=
