Reactive Red 24 Chemical Properties,Usage,Production
Chemical Properties
Red powder. Solubility in water (20 ℃) for 60g / L, (50 ℃) for 100g / L. The aqueous solution is red, add 1mol / L sodium hydroxide is still red, then add the insurance powder and warm to light yellow, and then add sodium perborate can not be returned to the original color. Red in concentrated sulfuric acid, still red after dilution, with slight precipitation; red in concentrated nitric acid, still red after dilution; red in dilute hydrochloric acid.
Uses
Reactive red 24 is a multifunctional dye. Dyes are important tools in biological experiments. They can help researchers observe and analyze cell structures, track biomolecules, evaluate cell functions, distinguish cell types, detect biomolecules, study tissue pathology and monitor microorganisms. Their applications range from basic scientific research to clinical A wide range of diagnostics. Dyes are also widely used in traditional fields such as textile dyeing, as well as in emerging fields such as functional textile processing, food pigments and dye-sensitized solar cells.
Preparation
4-Amino-5-hydroxynaphthalene-2,7-disulfonic acidand 2,4,6-Trichloro-1,3,5-triazine condensation, 2-Aminobenzenesulfonic acid diazo, coupled with condensation products, and then and N-methylbenzenamine condensation and salting-out.
Flammability and Explosibility
Not classified
Properties and Applications
blu-ray red. Red powder. The strong sulfuric acid for red, diluted is still red, and with a small amount of precipitation; In nitric acid for red, diluted in red. The dye solution for red, with 1 Moore sodium hydroxide solution is still red, continue to join insurance powder and warm, for light yellow, add a boric acid sodium is also can’t restore the original colour and lustre. Can be used for cotton or viscose fiber disseminated, roll dye, knot dyeing piled up dyeing. Can also be used to cotton or viscose fabric, the dye printing directly.
