Abstract：The preparation of 1-aminoanthraquinone from hydrogenation of 1-nitroanthraquinone using to prepare by adding hydrogen using Rane CAT-1000 as catalystwas studied.The influence of the process conditions including the dosage of catalyst, reaction pressure and reaction temperature etc. on the addition of hydrogen was explored and the related optimized process conditions were obtained. A typical preparation process was as following: Namely, 50 g of 1-nitroanthraquinone, 200 g of DMF(Dimethyl Formamide), the addition amount of catalyst is 3% of the nitro-group compounds, the reaction temperature is 70 ℃, the reaction pressure is 2 MPa, the reaction time is 1 hand the speed is 1000 r·min-1. Under this condition, the conversion rate of 1-nitroanthraquinone is close to 100%, and the selectivity of aminoanthraquinone is greater than 97.5%.
