ABSTRACT:
The present invention relates to improved reductive amination processes whereby monoethanolamine and ammonia are reacted in the presence of hydrogen and various reductive amination catalysts to yield high selectivity to acyclic products such as aminoethylethanol-amine, while reducing the production of cyclic products such as piperazine. When the process of the present invention is carried out in the presence of reductive amination catalyst containing metals such as nickel or nickel-rhenium on transitional alumina carriers, productivity and selectivity to the desired products is increased. Alternatively, the process may be carried out in the presence of hydrotalcite-like or takovite-like catalysts which have been enhanced by the use of promoters to achieve the desired results.
