【摘要】 报道了以4,4’-酸(4,4’-二氨基-二苯胺-2-磺酸)代替联苯胺,与H酸(1-羟基-8-氨基-3,6-二萘磺酸)、间苯二胺、苯胺等合成无致癌作用的环保型黑色直接染料。探索了合成工艺及反应条件,并对其应用性能进行测试。合成的染料在溶解度、耐酸、耐碱棉织物的牢度性能和上染率等方面与商品染料基本相当。更多还原

【Abstract】 4,4’-Diamino-dipenylamine-2-sulfonicacid was used as an alternative of benzidine,and reacted withl-hy droxy-8-aminonaphthalene-3,6-dusuifonicacid,m-benzioc-diamine and aniline to synthesize eco-friendly black direct dyes.The optimum reaction conditiors were investigateel,and the obtained dyes’application praperties were tested.compared to commercid dyes,the dyes have similor solubility resistarce to acid and alkali fastnesses and uptake on cotton.更多还原
