Studies on Modified Hydrogenation Catalyst. I. Selective Hydrogenation Activity of Modified Raney Nickel Catalyst for Carbonyl Group and C=C Double Bond

Abstract

Abstract Hydrogenation activity of the Raney nickel catalyst for carbonyl compounds was greatly diminished, when the catalyst was treated with a solution of amino acid. On the other hand, no appreciable change in its hydrogenation activity for C=C double bonds occurred upon this treatment. When mesityl oxide was used as a substrate, selective hydrogenation was most clearly demonstrated. The effect of conditions of modification, such as concentration of the modifying solution, immersion time and kind of modifying reagent on the activity of the modified catalyst, were investigated.
