Abstract

268,542. British Dyestuffs Corporation, Ltd., and Tatum, W.. W. March 19, 1926. 1-Oxy-2-sulpho - 4 - arylaminoanthraquinones, which are acid wool dyes and are described in Specification 21897/00, are obtained by the action of metallic sulphites on 1-oxy-2-halogen-4-arylaminoanthraquinones. In an example, 1-oxy-2- chlor-4-tolylaminoanthraquinone (obtained by heating 1-oxy-2 : 4-dichloranthraquinone with ptoluidine) is dissolved in phenol and heated with sodium sulphite solution in an autoclave. The phenol is then steamed off and the product is salted out. It dyes wool from an acid bath in fast reddish-blue shades.
