性质描述: 蓝黑色粉末,溶于水呈红光蓝至色,溶于酒精为藏青色,微溶于丙酮,不溶于其他有机溶剂。遇浓硫酸呈灰蓝色至黑色,将其稀释后呈喑绿光蓝色,遇浓硝酸呈红光棕色后转为黄色。其水溶液加浓盐酸呈绿光蓝色,加浓氢氧化钠液呈枣红色。染色时遇铜离子色泽绿暗,遇铁离子也较暗。
生产方法: 劳伦酸第一次重氮化后与甲萘胺盐酸盐偶合,所得的单偶氮化合物再进行第二次重氮化,再与苯基周位酸进行第二次偶合,盐析而得。工艺过程如下。甲萘胺 81 硫酸(100%) 165苯基周位酸(100%) 169 氢氧化钠(100%) 327劳伦酸 140 乙酸钠  155亚硝酸钠(98%) 97 元明粉  86盐酸(31%) 293 工业盐  1419
用途: 用于毛织物染色,特别适用于粗毛织品和毛/粘混纺织物,也适用于锦纶,丝绸和皮革的染色。其钡盐可做到颜料,
