Abstract

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 0.8-1.2 mm; average length 3-5 mm and 5-6 N/m breaking strength. The catalyst opt. treated by HCl and tetra-butyl-ammonium-hydroxide contains 0.2-5.0 wt.% Pli
