| Abstract：The synthesis of p-aminophenol by catalytic hydrogenation of nitrobenzene over Pt / active carbon catalyst was studied in the laboratory. Effects of some key parameters such as reaction temperature, pressure of hydrogen, pH value and reaction time was investigated. The optimum condition was as follow: reaction temperature 75℃, reaction time 4 h, pressure of hydrogen 2.45 kPa ,sulfuric acid concentration 13% and contents of catalyst 2%. |
| Key words：nitrobenzene; catalytic hydrogenation; p-aminophenol; Pt / active carbon catalyst |
