摘　　要： 以7 -乙酰氨基 -4 -羟基 -2- 萘磺酰氯为原料,通过与N,N- 二甲基乙二胺缩合反应及与间氨基苯基- β -羟 乙基砜硫酸酯重氮盐的偶合反应合成了含双萘环结构的通用染料。用质谱和核磁共振谱对染料及中间体的 结构进行了表征。该染料只需通过调节染浴的pH值和加入适当的染色助剂,就能用于对棉、羊毛、丝绸、尼 龙、腈纶和涤纶等各类纤维进行染色,上染率分别为6.2%、59.8%、44.7%、33.5%、11.1%和9.2%;对羊毛, 丝绸,尼龙有较好的亲和力,且水洗牢度均高于3级,但日晒牢度相对较低。 A new universal dye containing two naphthalene rings was prepared by condensation of 7-aceta- mide-4-hydroxy-2-naphthalene sulfonyl chloride with N,N-dimethylethylenediamine, followed by the coupling reaction with ammonium of m-amino-benzene-β-hydroxyethylene sulfonate. The chemical structures of the new dye and the intermediate were confirmed by Mass Spectrometry, 1H NMR and 13C NMR analyses. By adjusting the pH value of the dyebath and adding textile auxiliaries, the synthesized universal dye was applied to dye cotton, wool, silk, nylon, acrylic and PET fabrics without conducting other chemical reactions outside the dyebath. The exhaustion rates of dye on the fabrics aforementioned were 6.2%, 59.8%, 44.7%, 33.5%, 11.1% and 9.2%, respectively, which reveals that the dye has good affinity for wool, silk and nylon fabrics. The washfastness grades of dyed wool, silk and nylon fabrics were all higher than 3, while their lightfastness properties were not satisfactory.
