Method for catalytically hydrogenating aniline compounds by using nano-porous ruthenium-nickel catalyst

The invention belongs to the technical field of medicine and natural compound chemical intermediates and related chemistry, and provides a method for catalytically hydrogenating aniline compounds by using a nano-porous ruthenium-nickel catalyst. According to the method, aniline and derivatives thereof are used as raw materials, nano-porous RuNi is used as a catalyst, hydrogen is used as a hydrogen source, the aniline is efficiently subjected to hydrogenation reduction, and the pressure of the hydrogen is 0.5-3.0 MPa; the molar concentration of the aniline and the derivative thereof in the solvent is 0.01-2 mmol/mL. The pore skeleton size of the catalyst is 1-50nm, and the molar ratio of aniline and derivatives thereof to the catalyst is 1: 0.03-1: 0.1. The method has the beneficial effects that the product yield is high, the reaction condition is lower, the operation and post-treatment are simple, the catalyst repeatability is good, the catalytic effect is not obviously reduced after the catalyst is used for
