性质描述: 蓝灰色粉状物,溶于水呈深紫色至黑色,微溶于乙醇和溶纤素。遇浓硫酸呈蓝色,稀释后呈红光紫色;遇浓硝酸呈棕光紫色。其水溶液,加浓盐酸呈红光紫色;加浓氢氧化钠液呈枣红色。对纤维素纤维染色,染料吸尽性很好,温度在60-80℃亲合力最大,拔染性好。
生产方法: 以联苯胺、H酸和γ酸为基本原料。联苯胺经重氮化后,与H酸和γ酸进行双偶合,而后经盐析、过滤及干燥而得。公斤/吨联苯胺(100%) 82H酸(100%) 150γ酸(100%) 105亚硝酸钠(工业) 65盐酸(31%) 165纯碱(工业) 295元明粉 40
用途: 主要用于棉、粘胶等纤维素纤维织物的染色,也可用于蚕丝染色,还可用于皮革、纸张染色,以及拼制直接灰407#。本品染棉或粘胶得暗蓝色,如重氮化后再经乙萘酚显色得蓝灰至黑色,用间苯二胺显色得黑色。本品一般不用于染黑色,因手续麻烦。染黑色时,均选用直接黑BN或直接黑G。
