摘　　要：为了提高荧烷的耐光牢度,合成了一种新型染料3′,6′-二（N,N-二苯氨基）荧烷（DPAF）.首先,以间苯二酚和二苯胺作原料,85%磷酸作催化剂,在220 C高温下一步缩合得到中间体3-（N,N-二苯基）氨基苯酚（DPAP）,并对影响该反应的各因素进行了研究.其次,以对甲苯磺酸为催化剂,将DPAP与邻苯二甲酸酐在180C下环合,得到目标产物DPAF.最后,通过红外、质谱和~1H NMR验证了其结构.For the purpose of improving lightfastness,a novel dye 3′,6′-bis（N,N-diphenylamino） fluoran（DPAF） was desingned and its synthesis was studied.First,the m-dihydroxybenzene reacted with diphenylamine at 220℃with 85%H_3PO_4 as a catalyst to produce the intermediate 3-（N,N-dipbenyl）aminophenol（DPAP）.The influencing factor of the reaction was examined in detail.Then,the dye DPAF was synthesized by cyclization of the intermediate DPAP with phthalic anhydride at 180℃ in the presence of p-toluenesulfonic acid.Finally,the structure of dye DPAF was confirmed by IR,MS and ~1H NMR.
