| abstract | New 1-isocyanato-anthraquinones, such as. B. 1-isocyanato-anthraquinone, -5- or -8-nitroanthraquinone, -2-methylanthraquinone or chloroanthraquinones, which are valuable dye intermediates, are obtained in good yields if corresponding 1-aminoanthraquinones in phosgene or a solution of phosgene, in particular in o-dichlorobenzene, at -10 to 50 ° C., the reaction mixture is heated to 100 to 200 ° C. while passing phosgene through it, and then the phosgene and hydrogen chloride are expelled from the reaction mixture using an inert medium which is gaseous under the reaction conditions. |
