七只新酸性染料的合成

A Study on the Synthesis of Seven Acid Dyes

2-氨基苯酚-4-(2′-羧基)磺酰苯胺重氮化,分别与乙酰乙酰苯胺、2-萘酚、1-(3′-磺酰氨基苯基)-3-甲基-5-吡唑啉酮、尼文酸、1-乙酰氨基-7-萘酚等偶合,得到不同的偶氮化合物,然后分别与硫酸铬或氯化钴进行络合反应,得到黄、橙、红、紫、蓝多种颜色染料,并进行了毛织品的染色实验。目标产物色彩艳丽,牢度良好,潜在着较大的研究与开发价值[1]。

2 -Aminophenol -4 - （2＇ -carboxy） sulfonyl phenylamine was diazotized, then coupled with acetoacetanilide, 2 - naphthol, 1 - phenyl - 3 - methyl - 5 - pyrazolone, 1 - naphthol - 4 - sulfonic acid etc, respectively, obtained some diazo componnds. They were metallizated with potassium chromium sulfate or cobaltous chloride, got yellow, orange, red, purple and blue dyes. Their dyeing experiment was does on wool textile. These dyes have brilliant shade and good fastnesses. They provide potential values in research and developments.
