use | alkaline brilliant blue B can be used to dye silk, wool, hemp and tannin mordant cotton fiber, but the sun fastness is at grade 1-2. It is more used for coloring carbon paper and general paper, as well as for coloring bamboo and wood products and making lake pigments. It is used for dyeing typing wax paper, carbon paper and general paper. It can also be used for dyeing cotton, acrylic, hemp, silk, bamboo, wood, etc., and for making lakes. It is mainly used for dyeing paper, and can also be used for dyeing and manufacturing of cotton, acrylic fiber, hemp, silk, bamboo, wood, etc. Biological staining agents, such as nerve tissue, gum, blood, spirochete dyeing. |
Production method | From tetramethylmierone and N-phenylmethylnaphthylamine, in the presence of chloroform and phosphorus oxychloride, condensation, and then hydrolysis, purification, salting out, drying to obtain the finished product. Raw material consumption (kg/t)N-phenylmethylnaphthylamine 480 tetramethylmierone (100%) 560 chloroform 200 xylene 150 phosphorus oxychloride 330 sodium hydroxide (100%) 135 refined salt 480 yellow gum powder 88 Using tetramethylmierone [benzophenone, 4,4 '-bis(dimethylamino)] and N-phenyl-1-naphthylamine as raw materials, the two are condensed in the presence of phosphorus oxychloride, the finished product is obtained by hydrolysis, purification, salting out, drying and crushing.. |
