Abstract

The hydrotreatment of some aromatic amines was studied at temperatures ranging from 400 to 450°C and PH2=1 atm under flow conditions. Hydrogenolysis of aromatic amines involves direct cleavage of the C(sp2)---N bond without saturation of the aromatic ring. The presence of hydrogen sulphide in the reaction stream has a promotional effect on the hydrogenolysis of C(sp3)---N bond and an inhibitive effect on the hydrogenolysis of C(sp2)---N bond. The use of a saturated hydrocarbon as diluent facilitates C---N bond hydrogenolysis in the presence of hydrogen, irrespective of the carbon being sp2 or sp3 hybridized.
