性质描述: 白色针状结晶。溶于冰醋酸,微溶于热水,极微溶于冷水。
生产方法: 在生产克列夫酸过程中,得到混合的氨基萘磺酸镁盐,其中也含有1,8-氨基萘磺酸镁盐。这三种异构体镁盐在不同温度下有着不同的溶解度,操作时,先将混合液(还原液)浓缩到一定浓度,降温到30-32℃,先析出1,6-氨基萘磺酸镁盐(过滤后酸析得到1,6-克列夫酸);滤液加硫酸进行部分酸化,在40-45℃搅拌12h,过滤得到的就是1-萘胺-8-磺酸。滤液再继续酸析即得1,7-克列夫酸。原料消耗定额:精萘(99%)1206kg/t、硝酸(98%)605kg/t、铁粉1227kg/t、硫酸(98%)3463kg/t、白云石(含MgO20%)27.86kg/t。
用途: 用于制造一系列的苯胺染料及中间体,如苯基周位酸、甲苯基周位酸、氨基C酸、芝加哥酸、海军灰和硫化暗绿3GW等。
