Abstract
AbstractA description is given of the use of Raney cobalt for the hydrogenation of unsaturated and carbonyl linkages under mild conditions. The results are compared with those obtained with Raney nickel catalysts.A study has also been made of the promoter effects of triethylamine, chloroplatinic acid and combinations of these, on the activity of the Raney cobalt catalyst for the hydrogenation of carbonyl compounds. As in the case of Raney nickel, such effects are highly specific for the compound under investigation. The most notable effect occurred in the hydrogenation of benzaldehyde, where the use of triethylamine chloroplatinate as promoter resulted in a cobalt catalyst having an activity several times greater than an unpromoted catalyst.
