| Vat Blue 4 | English |
| Chemical Properties | blue needles with a metallic lustre |
| Mainly to dye cotton. | |
| Uses | Indanthrone (Pigment Blue 60) functions as a blue pigment or as a dye. |
| 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. | |
| 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; |
| A blue vat dye or pigment. The molecule consists oftwo anthraquinone nuclei linked through two –NHgroups. | |
| 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. |
| Blue needles with a metallic luster or fine fluffy deep blue powder. | |
| Air & Water Reactions | Insoluble in water. |
| Flash point data for Vat Blue 4 are not available. Vat Blue 4 is probably combustible. | |
| Flammability and Explosibility | Not classified |
| Indanthrone , Indanthren Blue RSand R, is prepared from 2- (or1-) aminoanthraquinone by potash fusion , in potassium phenolate , , orin 50 % potassium hydroxide , . Chlorination of indanthrone in sulfuric acidunder addition of 1 % or5%manganese dioxide(5 – 8 % or 13.8 – 14 % Cl) at 50 – 55 ?C affords dyes of slightly greener shades (Indanthren BlueGCD 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. |
| 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.] |
