Abstract

311,347. I. G. Farbenindustrie Akt.- Ges. May 9, 1928, [Convention date]. Addition to 286,669. Anthanthrone derivatives.- The condensation products of the parent Specification containing free amino groups in the molecule are treated with acylating agents. In examples the condensation product from monobromanthanthrone (1 mol.) (prepared by brominating anthanthrone in sulpiiuric acid solution according to Specification 260,998) and 1: 5-diaminoanthraquinone (1 mol.) is treated with benzoyl chloride; the product dyes cotton bluish-grey shades from a reddishviolet vat; anthanthronyl-1: 4-diaminoanthraquinone is treated with benzoyl chloride the product dyes cotton greenish-blue shades from a reddish-violet vat; the condensation product from dibromanthanthrone (1 mol) (example 3 of Specification 260,998) and 1: 5-diaminoanthraquinone (2 mols.) is treated with benzoyl chloride; the product is practically identical with the dyestuff described in example 4 of the parent Specification.
