Abstract

The present invention relates to improved reductive amination catalysts useful in the production of alkyleneamine compositions having lower levels of cyclic components. Although typical reductive amination catalysts contain nickel or nickel-rhenium on carriers such as alumina, silica, silica-alumina and silica-titania, it has been discovered that by using carriers selected from the transitional aluminas, improvements are obtained in both selectivity to acyclic products and in activity of the catalysts.
