Abstract:
The invention provides a method for the reductive amination of diethanolamine to form a product composition that includes piperazine (PIP) and aminoethylethanolamine (AEEA). A catalyst with a transitional alumina/second metal oxide support and a mixture of catalytic metals is used for the reaction which results in low levels of non-PIP and non-AEEA side products.
