摘 要:利用溴氨酸钠与间苯二胺进行芳胺化反应,再与溴代物缩合、水解,得到以戊二醛为活性基团的蒽醌型活性染料XB2。对芳胺化反应(获取色基1)的工艺参数进行了筛选和优化,适宜条件为:pH=9,SnCl:/CuSO。(n:n)=2:1,间苯二胺/溴氨酸钠(n:n)=1.5:1,色基1的收率为90%;通过紫外、红外和质谱对目标产物XB2进行了结构表征。用XB2对浸酸羊皮进行鞣制和染色试验的结果表明:当XB2用量达到浸酸羊皮质量的3%时,皮块的收缩温度达到72.5℃,皮块同时被染成蓝黑色;水洗牢度测试的结果表明,XB2的耐水洗牢度达到4~5级。Anthraquinone reactive dye XB2 with glutaraldehyde as reactive group was obtained by the following procedure : aromatic amination reaction happened between benzene -1,3 -diamine and 1 -amino- 4 -bromoanthraquinone- 2 -sulfonic acid sodium, then the intermediate - 1 product was condensed with another bromide compound to get pre - dye. The pre - dye was hy- drolyzed to produce the target product XB2. The best reaction conditions of aromatic amination reaction are as follows: pH = 9, SnCl2/CuSO4(n:n) =2:1, benzene -1, 3- diamine/ 1- amino - 4- bromoanthraquinone - 2- sulfonic acid sodium(n: n) = 1.5:1. At this condition, the yield of intermediate - 1 is 90%. UV - vis, FTIR and HPLC - MS are applied to identify the target product XB2. The target product is also applied to tanning and dyeing in pickled goat pelt. The shrinkage temperature (Ts) of leather is 72.5℃ when the dosage of XB2 is 3% (w/w) and the pelt is dyed dark blue. The result of water -washing experiment indicates that XB2 has a good washing fastness, which is grade 4 - 5.
