Vat Blue 4 Usage And Synthesis
Chemical Propertiesblue needles with a metallic lustre
UsesMainly to dye cotton.
UsesIndanthrone (Pigment Blue 60) functions as a blue pigment or as a dye.
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;
DefinitionA blue vat dye or pigment. The molecule consists of two anthraquinone nuclei linked through two –NH groups.
ReactionsAs 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 DescriptionBlue needles with a metallic luster or fine fluffy deep blue powder.
Air & Water ReactionsInsoluble in water.
Fire HazardFlash point data for Vat Blue 4 are not available. Vat Blue 4 is probably combustible.
Purification MethodsCrystallise 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.]
Properties and Applicationsred 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.
