C.I.Vat Blue 4,C.I.69800,CAS 81-77-6,442.42,C28H14N2O4,Cibanon Blue RS,Cibanon Blue RSJ

Molecular Formula:C₂₈H₁₄N₂O₄

Molecular Weight: 442.42

CAS Registry Number:81-77-6

Manufacturing Methods : commonly known as Indanthrone. (a) in the Potassium nitrate, Potassium chlorate, glucose or organic acid salt (such as Potassium formate or Potassium acetate or both the mixture) under the existence of, with Potassium hydroxide treatment 2-Aminoanthracene-9,10-dione; (b) in the ethanol Potassium hydroxide treatment with 2 – Amino anthraquinone, and put the mixture is exposed to the air, (C) in Copper (II) chloride dihydrate presence, 2 Moore’s 1-Amino-2-bromoanthracene-9,10-dione own condensation; (d) the 8-Nitro-9,10-dioxo-9,10-dihydroanthracene-1-sulfonic acid reduction into 8 – hydroxy amino – 1 – anthraquinone sulfonic acid, and then into blue anthrone disulfonic acid, then take off sulfonic group. Note: this dye with Sodium hydroxide and glucose part reduction, reoccupy air oxidation, or soluble in sulfuric acid, and precipitation, we can produce superfine dispersible.

Properties and Applications:  brilliant red light blue. Blue black powder. Insoluble in water, acetic acid, Pyridine , toluene, Xylene, Acetone and ethanol, slightly soluble in hot Chloroform, 2 – Chlorophenol and Quinoline. Alkaline reduction leuco for blue; Acid reduction leuco for red light blue. In concentrated sulfuric acid for brown, dilution after blue precipitation. Easy excessive oxidation and reduction, the solid water sensitive, no resistance to chlorine bleaching. Widely used in yarn leuco dye and super fine powder can be used for cotton and polyester/cotton blended fabric of the suspension milk dye, also can be used for cotton direct printing and resist printing. Also can dye rayon, nylon and vinylon. Can be used for Peacekeeping/cotton, polyester/cotton blended fabric two bath dyeing set. Can also be processed into organic pigments used in ink and paint.
