| Abstract: | 3,4-Dichloroaniline was prepared from 3,4-dichloronitrobenzene by catalytic hydrogenation. Three kinds of catalysts include Raney-Ni, 5% Pa/C and amorphous Ni alloy were investigated. Results showed that with amorphous Ni alloy as the catalyst, the hydrogenation afforded the product in yield and purity both exceeding 99%. The catalyst could be reclaimed for fifteen recycles without loss of activity. |
| Keywords: | amorphous Ni alloy 3 4-dichloroaniline catalytic hydrogenation catalyst |
