| uses | acid particle elements are mainly used for dyeing wool and silk, and also for leather dyeing (usually by Chrome Mordant dyeing), as well as paper, wood products, soaps, and the coloring and manufacturing of anodized aluminum inks. Biological staining, such as staining of central nervous tissue, pancreatic tissue, cellular spores, etc. mixture of the sodium salt of the sulfonated product of the alcohol-soluble black pigment. Biological staining, such as central nervous tissue, pancreatic tissue, cell spore staining. mainly used for leather, silk and wool dyeing, can also be made into Lake for color paper and printing |
| production method | with alcohol-soluble nigrosine as raw material, sulfonated with concentrated sulfuric acid, separated and washed with waste acid, the product was obtained by neutralization with sodium hydroxide. The final product was obtained by filtration and drying. Alcohol-soluble aniline black (C.I.50415) process: nitrobenzene, aniline and aniline hydrochloride together with iron or copper are heated at 180-200 °c to give the product. After Acid washing, washing, filtering, drying to obtain the finished product. Alternatively, the product can be obtained by heating nitrophenol (or nitrocresol), aniline, aniline hydrochloride together with a small amount of iron at 180-200 °c. After Acid washing, washing, filtering, drying to obtain the finished product. |
