Using 2 - nitrobenzyl alcohol as raw material, ethyl acetate as solvent, supported - Ni catalyst as catalyst, the 2 - aminobenzyl alcohol is prepared by liquid phase catalytic hydrogenation. The effects of different solvents, reaction temperature, pressure and the amount of activator are studied. The result shows the optimized technology is as follows：ethyl acetate as solvent, temperature is 50 - 60℃, pressure is 1.5 MPa,m（ eatalyst）/m（2- nitrobenzyl alcohol） is 1 ： 10. Under this condition,the yield of the product is 93.2%.
