| artificial dyes | that is aniline dyes or coal tar dyes, many kinds, a wide range of applications. Its disadvantage is that it is easy to fade by sunlight, aniline blue, bright green, methyl green and so on. In the production of attention to grasp the pH, and to avoid direct sunlight, but also after several years does not fade. Basic fuchsin is a Basic dye, dark red powder or crystalline, soluble in water (solubility 1%) and alcohol (solubility 8%). Basic fuchsin is widely used in biological production. It can be used to stain collagen fibers, elastic fibers, eosinophilic granules and nucleoplasm of central nervous tissue. In the biological production used to stain the vascular plant lignification wall, but also as the original algae, the whole red algae staining. In bacteriological smears, long used to identify mycobacterium tuberculosis. Deoxyribonucleic acid has been checked for use as a histochemical reagent in the Ergen's reaction. |
| Application | is used for dyeing cotton, acrylic, silk, leather, etc. The dyeing fastness of acrylic fiber is better. Can also be used for paper, feather, wheat straw, bamboo, wood, etc., can also be used to make lakes. mainly used for cotton, acrylic, silk, leather dyeing, can also be used for paper, feathers, straw, wood, it can also be used in the manufacture of Lakes for the preparation of Schiff reagent for the detection of aldehydes, and for the determination of some acid ions and metal ions by extraction spectrophotometry. Also used for photometric detection of bromine, nitrite and sulfur dioxide. Used as a maximal inhibitor in polarographic analysis. It is also used as a nuclear dye for biochemical analysis, which is the strongest nuclear dye, which can make the sticky prion, elastic tissue and magenta particle staining, central nerve nuclear staining, and the identification of Mycobacterium tuberculosis in bacteriology, analytical chemistry in the preparation of Schiff reagent test aldehydes. Redox indicator titrated with bromate. |
| production method | aniline, P-toluidine and o-toluidine are melted together with nitrobenzene and ferrous chloride for oxidative condensation, then it is dissolved and extracted with sulfuric acid, and then neutralized, salting out, filtered and dried to obtain the finished product.
