Abstract

Alkyoxyanthraquinones are prepared by treating aryloxyanthraquinones with solutions of alkali metals or alkali metal hydroxides in monohydric alcohols. In examples (1) 1-phenoxyanthraquinone is treated with a solution of potassium hydroxide in methanol, ethanol or butanol to give 1-methoxyanthraquinone or the corresponding ethoxy or n-butyloxy derivative; (2) 1 : 4-diamino-2-phenoxy-anthraquinone is treated with a solution of potassium hydroxide in methanol, ethanol or n-butyl alcohol to give 1 : 4-diamino-2-methoxyanthraquinone or the corresponding ethoxy or n-butyloxy derivative; (4) 1 : 4 - diamino - 2 : 3 - diphenoxyanthraquinone is treated with a solution of potassium hydroxide in methanol, ethanol or butanol to give 1 : 4-diamino-2 : 3-dimethoxyanthraquinone or the corresponding diethoxy or dibutoxy derivatives; (5) 1-phenoxyanthraquinone is treated with a solution of potassium in methyl alcohol to give 1-methoxy-anthraquinone.
