CHLORANTINE FAST RED 5B Chemical Properties,Usage,Production

Chemical Properties

Brown powder. Good water solubility, soluble in ethylene glycol ether, slightly soluble in ethanol, insoluble in other organic solvents. Its aqueous solution is magenta, adding concentrated hydrochloric acid produces a yellowish olive-brown precipitate, adding concentrated alkali produces a purple precipitate. In concentrated sulfuric acid is dark blue, diluted to produce light orange-brown precipitate; in concentrated nitric acid is bright blue to red light brown. The color and light are basically unchanged when encountering iron ions in dyeing, and the color and light are slightly blue when encountering copper ions.

Uses

Chlorantine Fast Red 5B is a direct dye used in cosmetics, hair dyes and in the textile industry as a colourant.

Definition

ChEBI: An organic sodium salt resulting from the formal condensation of Sirius red 4B (acid form) with two equivalents of sodium hydroxide. Used as the plasma stain in some trichrome staining methods.

Preparation

4-((4-Aminophenyl)diazenyl)benzenesulfonic acid?diazo, and 7-Benzamido-4-hydroxynaphthalene-2-sulfonic acid coupling.

Flammability and Explosibility

Non flammable

Biochem/physiol Actions

Bacterial consortium NBNJ6 has an ability to decolorize direct red 81 (DR81).

Properties and Applications

red. Red powder. Soluble in water for product red, soluble in soluble fiber element, slightly soluble in alcohol, insoluble in other organic solvents. The strong sulfuric acid dyes for dark blue, shallow orange brown after diluted precipitation; In nitric acid solution for colourful blue, to red light brown. The dye solution to join strong hydrochloric acid for yellow olive brown precipitation; Add thick sodium hydroxide solution has the purple precipitation. 60 ℃ in the solubility of 40 g/L, not sensitive to that fights. For colourful red light. Copper ions in dyeing color slightly turn blue, encounter iron ion colored light basic unchanged. For A class SDC classification. To dead cotton cover the gender is poorer. Cotton neutral and alkaline white are level 5, viscose and minus sex of neutral white for 4 ~ 5 levels. Used for dyeing cotton and viscose, also can be used for paper color.
