| Isoviolanthrone , Formerly prepared from 3-halobenzanthrone by alcoholic potash melt.Isomer-free isoviolanthrone is obtained by analcoholic potash melt of 3,3'-dibenzanthronylsulfide or by the one-pot method . Dichlorination of isoviolanthrone with sulfurylchloride, or alternatively bromination inchlorosulfonic acid, affords brilliant violet vatdyes 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.] | |||||||||||||||||
