PROCESS FOR PRODUCING CHLOROANILINES FROM CHLORONITROBENZENE BY HETEROGENOUS HYDROGENATION UNDER PRESSURE
3,4-di:chloro-anilines are prepd. from o-, m-, p-, -chloro-nitro-benzenes and 3,4-di:chloro-nitro-benzene by hydrogenation at 50-150 deg. C and 3-15 MPa pressure using fixed bed catalyst. - Hydrogenation is carried out on 60-80% porous gamma-Al2O3 of a specific surface: 120-160 m2/g; average dia. is...
