| | Vat Violet 10 Usage And Synthesis |
| Preparation | commonly known as Isoviolanthrone.(a) 7H-benzo[de]anthracen-7-one?chlorinated, with Potassium hydroxide of Etanol solution treatment; (b) 7H-benzo[de]anthracen-7-one?and Potassium hydroxide of Etanol solution in Xylene, Chlorobenzene or kerosene in heating; (c) 3-Chloro-7H-benzo[de]anthracen-7-one?the anthrone into corresponding sulfide or selenide and then use alkali treatment. | | Synthesis | Isoviolanthrone , Formerly prepared from 3-
halobenzanthrone by alcoholic potash melt.
Isomer-free isoviolanthrone is obtained by an
alcoholic potash melt of 3,3'-dibenzanthronyl
sulfide or by the one-pot method .
Dichlorination of isoviolanthrone with sulfuryl
chloride, or alternatively bromination in
chlorosulfonic acid, affords brilliant violet vat
dyes and pigments.
 | | Purification Methods | Dissolve isoviolanthrone in 98% H2SO4 and precipitate it by adding water to reduce the acid concentration to about 90%. It sublimes in vacuo to give dark green-violet needles [Parkyns & Ubblehode J Chem Soc 4188 1960]. [Beilstein 7 I 465, 7 II 815, 7 III 4538, 7 IV 2747.] | | Properties and Applications | blue light purple. Soluble in 2 – Chlorophenol, Xylene to red, fluorescence, slightly soluble in Acetone, Chloroform, Pyridine and Toluene, insoluble in Etanol. In concentrated sulfuric acid for SAP green, purple precipitation after dilution, In the basic insurance powder solution for dark red light blue, in acid insurance powder solution for wine.
