    Abstract: The starting material is a hydrogenation product obtained by catalytic hydrogenation of 1-nitroanthraquinone in a reaction medium in the presence of a catalyst. The catalytic hydrogenation reaction product is treated with a solution of an inorganic base in water, an organic solvent or a mixture thereof. 1-Aminoanthraquinone is an important intermediate for the preparation of anthraquinone-based dispersions and vat dyes and pigments. The process is simple to carry out and gives a high yield of highly pure 1-aminoanthraquinone.
