Vat Yellow 2 Usage And Synthesis
Preparation
(a) 2, 6-Diaminoanthraquinone, 1-(Trichloromethyl)benzene and sulfur in the beta backflow; (b) will be 2, 6-diamino-1, 5-dimercapto-anthraquinone and Benzaldehyde ?and sulfur condensation;(C) 2,6-Diamino-1,5-dichloroanthraquinone and Benzaldehyde?and sulfur condensation; (d) 2,6-Dibenzamidoanthraquinone?into the amino chloride [2, 6-bis (1-chloro-methylene) anthraquinone], then use sulphur and naphthalene hydrogenated sodium sulfide solution or sulfur. Note: the product contains 1,2,7,8-heterogeneous content.
Synthesis
2,8-Diphenylthiazolo anthra- thiazole-6,12-quinone is prepared from 2,6-diaminoanthraquinone and benzaldehyde or benzotrichloride and sulfur in molten naphthalene.
