补充资料:直接紫酱
分子式:C32H22N6Na2O7S2
分子量:712.69
CAS号:暂无

性质:棕褐色粉状。溶于水呈酒红色,在乙醇中呈品红色,能溶于溶纤维,不溶于其他有机溶剂。遇浓硫酸呈蓝色,稀释后紫酱色沉淀;遇浓硝酸呈棕黄色。其水溶液加浓盐酸生成紫色沉淀,加浓氢氧化钠液生成橙棕色沉淀。对纤维素纤维染色,染料吸尽性很好,温度在80-100℃亲合力最大。

制备方法:联欢苯胺重氮化后,与1,4-氨基苯磺酸钠进行第一次偶合,而后又与γ酸进行第二次偶合,然后经盐析、过滤及干燥而得。原料消耗(kg/t)联苯胺(100%) 1701,4-氨基萘磺酸钠(100%) 230γ酸(100%) 220纯碱(工业纯) 270亚硝酸钠(工业纯) 145工业盐 2100盐酸(31%) 290

用途:用于棉、粘胶、蚕丝、锦纶及粘/棉混纺织物的染色,也可用于纸、皮革染色。除染色外,还可用于直接印花,还经常直接黄、橙、紫、棕、黑等染料拼色使用。可采用固色剂Y和M,以提高牢度。可用酰替苯胺结构的直接枣红NGB提高牢度。
