摘　　要：以2,7-二溴-9-芴酮和苯胺盐酸盐为原料,以甲苯为溶剂,亚硫酸氢钠为助催化剂,在氮气保护一定温度下催化合成9,9-双(4-氨基苯基)-2,7-二溴芴。粗产品采用重结晶的方法进行精制,精制溶剂选用甲苯与无水乙醇的混合液,重结晶产品经抽滤、干燥等处理得到相应的精制产品,并对产品进行了红外核磁等表征。产品通过液相测定纯度为99.50%,精制后产品收率为67.91%。The 2,7-dibromo-9,9-bis（4-aminophenyl）fluorene was synthesized through the catalytic reactions of 2,7-dibromo-9-fluorenone and aniline hydrochloride in methylbenzene solvent with sodium hydrogen sulfite as co-catalyst at a certain temperature under nitrogen protection. The crude product was refined by the recrystallization. The refining solvent was the mixture of toluene and ethanol. The recrystallized product was treated by suction filtration and drying to get the refined product. And the product was characterized by IR and NMR, etc. Its purity was 99.50%, and the yield of product was 67.91% after purification determined by liquid chromatogram.
