| Abstract: | 4-Hydroxybenzonamide was synthesized through 4-hydroxybenzonitrile by using Raney-Ni as catalyst. Influential factors, such as time （from 5h to 11h）,temperature （from 50℃ to 85℃） and pressure （from 0.3MPa to 0.8MPa） were investigated, and the appropriate reaction conditions were given： reaction pressure is 0.7MPa, reaction time is 9h, stir speed is 600 r.min^-1, reaction temperature is 70℃. |
