摘要 |
The present invention is directed to catalyst compositions containing nickel, copper, chromium and iron which are useful for promoting reductive amination reactions, such as the conversion of feedstocks containing one or more hydroxyl groups to corresponding amine compounds including acyclic, cyclic and heterocyclic amines. For example, the catalyst compositions of the present invention may be utilized to convert monoethanolamine to ethylenediamine and piperazine, for the conversion of diethylene glycol to morpholine and diglycolamine, etc.
