| Synthesis | 5,5'-Bisbenzoylamino-1,1'-dianthrimide-2,2'carbazole , Indanthren Golden-Orange 3G, is prepared from 5,5'-bisbenzoylamino-1,1'-dianthrimide by ring closurein concentrated sulfuric acid . | ||||||||||||||||||||||||||
| Pyranthrone , (149),is prepared by double ring closure of 2,2'-dimethyl-1,1'-bianthraquinonyl (148), which isobtained from 1-chloro-2-methylanthraquinone(147) by heating with copper powder in odichlorobenzene– pyridine. Ring closure occursunder alkaline conditions, e.g., KOH– isobutanolat 105 ?C ; process improvementsare reported in , . The unsubstitutedpyranthrone and its halogen derivatives are usedas vat dyes and pigments. | |||||||||||||||||||||||||||
| Properties and Applications | yellow orange. Orange powder. Soluble in 1, 2, 3, 4-Tetrahydronaphthalene and Xylene, slightly soluble in alcohol. In the dark for the strong sulfuric acid, dilute yellow brown after precipitation. Alkaline reduction for blue-ray red body hidden color; Acid reduction to orange color body hidden. This product for light brittle dye, cotton fiber in the sunlight has accelerated. With light brittle, general is not used for cotton cloth of monochromatic dyeing, spelling color also should control consumption, but also can directly printing and the discharge, also can be used in viscose, silk dyeing. Dye polyester/cotton blended fabric, of polyester dyeing serious.
