c.i.directblack38
性质描述: 棕黑色粉状物。溶于水呈绿光黑色,稍溶于乙醇,呈绿光蓝黑色,溶于溶纤素,不溶于其他有机溶剂。遇浓硫酸呈深红光蓝色,稀释后呈紫酱色至红光黑色沉淀;在浓硝酸中呈黄棕色溶液;在浓盐酸中呈暗红光黑色溶液。其水溶液加浓盐酸呈紫酱色沉淀。加浓氢氧化钠液,则生成灰色沉淀。对纤维素纤维染色,染料吸尽性很好,温度在80℃亲合力最大。可以拔染。
生产方法: 以联苯胺的、H酸、苯胺和间苯二胺为基本原料。联苯胺经重氮化,与H酸进行偶合(第一次偶合),苯胺重氮化后与第一次偶合物进行第二次偶合,接着与间苯二胺进行第三次偶合,然后经盐析,过滤及干燥而得。公斤/吨联苯胺(100%) 180苯胺 80H酸(100%) 300间苯二胺(100%) 70纯碱(工业) 190亚硝酸钠(工业) 195碳酸钙 25盐酸(31%) 550氨水(20%) 150元明粉 40
用途: 主要用于棉、麻、粘胶等纤维素纤维织和的染色,也可用于蚕丝、锦纶及其混纺织物的染色,还可用于皮革、生物和木材的染色、塑料的着色及作为赤色墨水的原料等。直接黑BN为常用黑色染料,较多单独用于黑色,也常与棕色拼成各种咖啡色。
