Abstract
The present invention provides catalyst compositions useful for transamination reactions. The catalyst compositions have a catalyst support that includes transitional alumina, use a low metal loading (for example, less than 25 wt. %), and do not require the presence of rhenium. The catalyst compositions are able to advantageously promote transamination of a reactant product (such as the transamination of EDA to DETA) with excellent activity and selectivity, and similar to transaminations promoted using a precious metal-containing catalyst.
