Abstract

249,099. Soc. of Chemical Industry in Basle. March 10, 1925, [Convention date]. Addition to 231,555. Anthraquinone-azines. - The vat dyestuff described in the parent Specification is obtained by treating a 1-halogen-2-aminoanthraquinone- 3-carboxylic acid with an agent which eliminates hydrogen halide and then purifying the product in the known manner. According to an example, 1-brom-2-aminoanthraquinone-3-carboxylic acid is boiled with nitrobenzene, sodium acetate, and copper chloride, and the product extracted with sodium carbonate to remove unchanged parent material and then purified. 1 - Halogen - 2 aminoanthraquinone - 3 - carboxylic acids are obtained bv treating the parent acid with halogen; bromine in glacial acetic acid is specified.
