性质描述:

该品为白色或灰白色针状晶体。常含有1.5个结晶水。易溶于热水，能溶于碱溶液，难溶于冷水，微溶于醇和醚。与三氯化铁作用呈棕红色，酸性盐带蓝红色荧光，加碱后变为红紫色，溶于碱性溶液呈深绿色。

生产方法:

以萘为原料生产H酸单钠盐包括以下步骤：（1）萘磺化得1,3,6-萘磺酸；（2）1,3,6-萘三磺酸硝化生成1-硝基-3,6,8-萘三磺酸，并使硝化混合物脱尽二氧化氮；（3）硝化混合物用氨水中和；（4）中和产物硝基萘三磺酸三铵盐还原，用硫酸和食盐析出还原酸化产物T酸；(5)将T酸转变成钠盐，碱熔、酸析得到H酸单钠盐：由萘制取H酸单钠盐的步骤较多，总收率一般为46%-50%。工业用产品为浅灰至灰色膏状物，H酸单钠盐含量为42%。粉状物H酸单钠盐含量为83.5%以上（GB-1648-84）

用途:

该品为重要的染料中间体。
