性质描述:

灰色至黑色粉状物。溶于水呈黑色，在浓硫酸中呈红紫色，稀释后有黑紫色沉淀；在浓盐酸中有黑色沉淀；在浓烧碱液中有暗紫色沉淀。

生产方法:

由4，4'-二氨基二苯胺-2-磺酸重氮化（一次重氮化），与γ-酸进行偶合（一次偶合），一次偶合物再重氮化（二次重氮化），而后与2-（间氨基苯胺基）乙醇进行偶合，然后经盐析、过滤及干燥而制得。

用途:

本品的染棉或粘胶织物得青光灰至黑色。染蚕丝和粘胶丝交织物时，宜以酸性染料套染蚕丝，从而得到双色效果，染锦纶得红光灰色。染涤纶、腈纶得极浅灰色。本品以前广泛用于粘胶织物，针织物和绒毯等织物的染色和印花，色光较直接灰D稍灰与黄，再已用直接灰D代替。
