Abstract: Hydrogenation of oligonitriles exhibiting at least two nitrile groups, in the presence of a catalyst, which is pre-treated before the hydrogenation process by contacting with a compound A, where the compound A is alkaline metal carbonates, alkaline-earth metal carbonates, ammonium carbonate, alkaline metal hydrogencarbonate, alkaline-earth metal hydrogencarbonate, ammonium hydrogencarbonate or alkaline-earth metal oxycarbonate. Independent claims are included for: (1) an oligo amine or amino nitrile, obtained from an oligo nitrile; (2) a catalyst comprising a metal from group VIII to X, which is pretreated with the compound A, where the cobalt or nickel catalyst is pre-treated with compound A excluding alkali metal carbonate or alkali metal hydrogen carbonate; and (3) a method for preparing the catalyst comprising treating a metal from the group VIII to X with the compound A.

Abstract: A method for the production of tetrahydrogeranylacetone is disclosed, whereb y pseudoionone, geranylacetone and/or dihydrogeranylacetone in the liquid phas e, in which particles of a catalyst, for the preferential hydrogenation of carb on- carbon double bonds before carbon-oxygen double bonds, are suspended, is fed through a device along in the presence of a gas comprising hydrogen, said device preventing the transport of the catalyst particles.
