摘要
The present invention relates to a method for continuously hydrogenating a nitro compound to give the corresponding amine in a liquid reaction mixture containing the nitro compound, in the presence of a supported catalyst which contains as the active component at least one element from groups 7 to 12 of the periodic table of the elements, the hydrogenation being carried out in the presence of at least one salt selected from the group consisting of the salts of the alkali metals, alkaline earth metals or rare earth metals. The invention also relates to a supported catalyst for continuously hydrogenating a nitro compound to give the corresponding amine in a liquid reaction mixture containing the nitro compound and, as the active component, at least one element from groups 7 to 12 of the periodic table of the elements and at least one salt of the alkali metals, alkaline earth metals or rare earth metals.
