Abstract

253,386. Johnson, J. Y., (Badische Anilin & Soda Fabrik). Aug. 12, 1925. Samples furnished. 1 : : 1<1>-dianthraquinonyl-2: 2<1>-dialdehyde and its halogen derivatives are obtained by the reaction of cuprous halogenides on diazotized 1- amino-2-anthraquinone aldehyde or its halogen derivatives, preferably in the absence of additional chlor ions. In examples, 1: 1<1>-dianthraquinonyl-2 : 2<1>-dialdehyde is obtained by diazotising 1-amino-2-anthraquinone aldehyde in sulphuric acid solution and heating with a solution obtained by boiling copper sulphate, sodium chloride, and sodium bisulphite with water, and 4 : 4<1>-dichlor-1 : 1<1>-dianthraquinonyl-2 : 2<1>-dialdehyde is similarly obtained from 4-chlor-1-amino-2- anthraquinone-aldehyde. 4 - chlor - 1-amino-2 anthraquinone-aldehyde is obtained by acting on 4-chlor-1-amino-2-methylanthraquinone with nitrosyl chloride and treating the 4-chlor-1-azido-2-anthraquinone-aldehyde thus obtained with an alkaline sodium hydrosulphite solution
