CAS: 81-05-0
分子式: C10H9NO3S
分子量: 223.25
中文名称: 
6-氨基-1-萘磺酸
2-萘胺-5-磺酸
6-氨基础萘磺酸
英文名称: 
6-amino-1-Naphthalenesulfonic acid
2-Naphthylamine-5-sulfonic aci
1-Naphthalenesulfonic acid,6-amino-
6-Aimino-1-naphthalenesulfonic acid
Dahl's acid
2-Naphthylamine-5-sulfonic acid
性质描述: 白色针状结晶。易溶于水,几乎不溶于醇,水溶液呈红蓝色荧光。
生产方法: 由β-萘胺经磺化而得。磺化反应在50-60℃下进行,生成2-萘胺-5-磺酸和2-萘胺-8-磺酸的混合物,用水稀释后加氢氧化钠溶液调至pH为9,过滤蒸发得到钠盐。然后用乙醇提取分离,将提取液蒸干得2-萘胺-5-磺酸钠盐,然后经水解、酸化即得成品。
用途: 用作染料中间体。
