性质描述: 针状或叶状结晶。熔点286℃。溶于沸水,稍溶于乙醇,乙醚,微溶于水。
生产方法: 以对氨基苯磺酸钠为原料,与水及30%的盐酸混合,冷却至2℃。然后在0-5℃滴加亚硝酸钠溶液,使对氨基苯磺酸钠重氮化。将上述重氮液加入氢氧化钠溶液和重亚硫酸钠的混合液中,加料温度控制在80-85℃,pH值保持6.2-6.7。加毕,继续搅拌1.5h,再加入锌粉、硅藻土、搅拌过滤。将此反应产物用酸处理,即得苯肼-4-磺酸。
用途: 该品是染料柠檬黄的中间体,也用作冰染染料防染剂。苯肼-4-磺酸与苯乙烯基对氯苯酮缩合,可制得增白剂提诺帕尔WG(Tinopal WG)。这种增白剂主要用于羊毛、丝绸和锦纶的增白。
