| Hazard Information | Back Directory | [Chemical Properties]
blue needles with a metallic lustre | [Uses]
Mainly to dye cotton. | [General Description]
Blue needles with a metallic luster or fine fluffy deep blue powder. | [Air & Water Reactions]
Insoluble in water. | [Fire Hazard]
Flash point data for Vat Blue 4 are not available. Vat Blue 4 is probably combustible. | [Preparation]
(a) in potassium nitrate, LvSuanJia, glucose or organic acid salt (such as formic acid potassium or acetic acid potassium or the mixture of both) under the existence of, with potassium hydroxide treatment 2-Aminoanthracene-9,10-dione; | [Reactions]
As a pigment, indanthrone is a particulate, insoluble solid dispersed directly into a vehicle, whereas as a dye it is reduced to a base-soluble hydroquinone derivative and then reoxidized onto a solid substrate. | [Flammability and Explosibility]
Notclassified(100%) | [Synthesis]
Indanthrone , Indanthren Blue RS
and R, is prepared from 2- (or
1-) aminoanthraquinone by potash fusion , in potassium phenolate , , or
in 50 % potassium hydroxide , .
Chlorination of indanthrone in sulfuric acid
under addition of 1 % or5%manganese dioxide
(5 – 8 % or 13.8 – 14 % Cl) at 50 – 55 ?C affords
dyes of slightly greener shades (Indanthren Blue
GCD or BC). | [Properties and Applications]
red light blue. Slightly soluble in chloroform (heat), o-chlorophenol,Quinoline, insoluble in acetic acid, acetone, ethanol, pyridine, toluene, xylene. The strong sulfuric acid for brown, after diluted blue precipitation; In alkaline insurance powder solution for blue, acidic solutions for the red light in blue. And C.I. Vat ?Blue 4, C.I. Pigment Blue 60 the same chemical structure. | [Purification Methods]
Crystallise indanthrene repeatedly from 1,2,4-trichlorobenzene to give a blue powder. It is soluble in alkali and conc H2SO4. [Weinstein & Merritt J Am Chem Soc 81 3759 1959, Beilstein 24 II 317, 24 III/IV 2193.] |
