p-Fluorobenzyl amine was prepared using p-fluorobenzaldehyde, ammonia and hydrogen gas as raw materials, ethanol as solvent and Raney Ni as catalyst. The pressure of H2 was 1.5-2.0 MPa. The influence of reaction conditions to yield and conversion were under investigation and the optimum condition was determined. The optimum condition is: n(p-fluorobenzaldehyde):n(NH3)=1.0:2.5, w(p-fluorobenzaldehyde):w(ethanol)=1.0:1.3, reaction temperature: 60-65oC, the amount of Raney Ni is 5 wt% of p-fluorobenzaldehyde, reaction time: 7-8 h. Under this condition, the selectivity from p-fluorobenzaldehyde to p-fluorobenzyl amine is 95.3%, the yield is more than 85% and the purity of p-fluorobenzyl amine is >99% after purification.
