性质描述: 金黄色粉末。溶于水呈红光黄色,溶于乙醇呈橙色,于浓硫酸中为品红色,将其稀释后生成棕黄色沉淀。其水溶液加盐酸生成棕黄色沉淀,加氢氧化钠呈深棕色。染色时遇铜离子趋向红暗,遇铁离子色泽浅而暗。拔染性好。
生产方法: 双氨基苯磺酸钠重氮化,与-2-萘酚偶合,盐析而得。工艺过程:将15%左右的浓度的对氨基苯磺酸钠溶液(100%173kg)和30-35%浓度的亚硝酸钠溶液(100%69kg)加入混合桶内搅匀。在重氮桶内加水600L。加入适量冰,搅拌下加入30%盐酸264kg,控制温度10-15℃,将混合桶的物料于10min左右均匀加入重氮桶,于10-15℃,保持酸过量,亚硝酸微过量的条件下搅拌0.5h,得得氮为悬浮体。于偶合桶内加水400L,2-萘酚141.8kg,搅拌下将液碱(30%)143kg加入,升温到45-50℃,使之溶解后加冰冷却到8℃,加盐19kg,快速加入重氮盐全量的一半。再加盐37kg,然后将另一半重氮盐在1h内均匀加完,并调整pH.1搅拌1h,再加盐75kg,继续搅拌至重氮盐消失为偶合终点(约1h)。压滤,滤饼于100-105℃烘干。得标准化染料880kg。2-萘酚 352 碳酸钠(98%) 57对氨基苯磺酸钠(100%) 496 盐酸(31%) 97亚硝酸钠(98%) 175 元明粉  10硫酸(100%) 255 精盐  70氢氧化钠(100%) 96 太古油  11
用途: 主要用于蚕丝,羊毛织品的染色,也可用于皮革,纸张的染色。在甲酸浴中可染锦纶。该品可在毛,丝锦纶上直接印花,也可用作指标剂和生物着色。
