| | Vat Blue 4 Usage And Synthesis |
| Chemical Properties | blue needles with a metallic lustre | | Uses | Dinaphtho[2,3-a:2'',3''-h]phenazine-5,9,14,18(6H,15H)-tetraone is a pigment; used in preparation of Polyethylene composite material for outdoor building materials. | | Uses | Indanthrone (Pigment Blue 60) functions as a blue pigment or as a dye. | | Uses | Mainly to dye cotton. | | 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; | | Definition | A blue vat dye or pigment. The molecule consists of
two anthraquinone nuclei linked through two –NH
groups. | | 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. | | 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. | | Flammability and Explosibility | Not classified | | 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.
