| | Disperse Blue 14 Usage And Synthesis |
| Description | Disperse blue 14 is also known as transparent blue GP. Its chemical name is 1,4-bis(methylamino)anthraquinone. It is a blue-black powder, insoluble in water, soluble in methanol, ethanol, glacial acetic acid, nitrobenzene, pyridine and toluene. It is reddish brown in concentrated sulfuric acid. | | Uses | 1,4-Bis(methylamino)anthraquinone can be useful in freshwater production by solar desalination of seawater using two-ply dye modified membrane system. | | Preparation | 1,4-Dihydroxyanthracene-9,10-dione?by under pressure,?With aqueous Methanamine?and sodium hydrosulfite or zinc processing. Leuco sulfate nitrobenzene oxidation or thermal | | Properties and Applications | bright blue. Blue powder. Soluble in acetone, glacial acetic acid, the difficulties, pyridine and toluene. The strong sulfuric acid to red light brown. Used for polyester, vinegar and polyamide fiber dyeing, also can be used to transfer printing. And is fit for manufacturing fireworks fireworks hair color components. Can also be used in such of surface colouring and plastic.

| | Purification Methods | Purify the anthraquinone by thin-layer chromatography on silica gel plates, using toluene/acetone (3:1) as eluent. The main band is scraped off and extracted with MeOH. The solvent is evaporated and the dye is dried in a drying pistol [Land et al. J Chem Soc, Faraday Trans 1 72 2091 1976]. It crystallises from n-butanol with m 221-222o and has max 539 and 644nm (EtOH). [Beilstein 14 H 198, 14 III 440, 14 IV 459.] |
