Abstract

296,817. Carpmael, A., (I. G. Farbenindustrie Akt.-Ges.). June 10, 1927. Anthraquinone vat dyes.-Anthrone or its homologues and halogen substitution products are condensed with glyoxal or its bisulphite compound, sulphuric acid ester, or other compound capable of giving rise to glyoxal with or without the use of a solvent, or of an acid or acid reacting salt. The products are vat dyes giving yellow shades on cotton. Examples are given of the condensation of anthrone and the chloro anthrone prepared by reduction of alpha-chloranthraquinone with glyoxal sulphate in glacial acetic acid.
