Abstract

339,266. Carpmael, A., (I. G. Farbenindustrie Akt.-Ges.). Sept. 3, 1929. Anthraquinone dyes are made by causing 1- amino-4-bromoanthraquinone-2-sulphonic acid to react with an aromatic amine containing a hydroxy group, which is etherified by a polyvalent alcohol. The reaction is promoted by the presence of copper or a copper salt. In examples, the sulphonic acid is heated in the presence of aqueous sodium carbonate and a small amount of copper sulphate with (1) o- or p-aminophenolglycolether, (2) p-aminophenolglycerolether. The products dye wool in even clear blue and greenish blue shades. Specification 10378/14 is referred to.
