Abstract
Abstract The invention relates to a ruthenium promoted nickel and/or cobalt dehydrogenation-hydrogenation catalyst. The ruthenium on the catalyst is applied from a solution containing a ruthenium halide compound. The catalyst use in organic reactions and a process performed in its presence are also described. Preferably, the catalyst is used to aminate alkylene oxides, alcohols, phenols, alkanolamines, aldehydes, and ketones.
