| Abstract: | 1 - Aminoanthraquinone was prepared by catalytically hydrogenating 1 - nitroanthraquinone with Pd/A1203 as the catalyst in a mixed solvent system. The effects of reaction temperature, stirring rate and reactant concentration, etc. on product purity were studied in orthogonal tests, and the optimum process conditions were identified as follows： the mass ratio of 1 -nitroanthraquinone, mixed solvent and Pd/A1203 is 10 ： 100 ： 0.1, reaction temperature is 70℃ , reaction time is 80 rain, hydrogen pressure is 1.0 MPa, and stirring rate is l 000 r/min. The product purity is higher than 98.5% and the yield is 97.5% at such conditions. |
