摘　　要：以间苯二胺和对苯二胺为反应芳胺，分别与溴氨酸通过乌尔曼缩合生成合间苯二胺基团的蒽醌型弱酸性染料A和含对苯二胺基团的蒽醌型弱酸性染料B，并采用红外光谱、核磁氢谱、质谱、紫外一可见光谱等分析方法验证了产物的分子结构，而且改进的实验方法使染料产率得到提高。将两只染料分别用于蚕丝织物染色，结果发现两只染料在蚕丝织物上的上染率均较高（96％以上）、耐日晒牢度为5～6级、耐摩擦和耐水洗牢度稍差，且染料B着色蚕丝织物的各项色牢度优于染料A。This research produces anthraquinone weak acid dye A containing m-phenylenediamine group and anthraquinone weak acid dye B containing p-phenylenediamine group with m phenylenediamine and p-phenylenediamine as reactive arylamine which respectively condense with bromamine acid through Uhlmann; verifies the molecular structure of the product with analytical methods such as infrared spectros- copy, nuclear magnetic resonance, mass spectrum and ultraviolet-visible spectrum. The improved experi- mental method improves the productivity of dyes. The result of using both dyes respectively for dyeing of silk fabric shows that both dyes have a high dye-uptake （over 96%） on silk fabric, color fastness to sunlight of grade 5-6 and poor fastness to rubbing and washing; moreover, various color fastnesses of silk fabric dyed by dye B are better than dye A.
