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.

Abstract: Cyclic ketal compounds provide excellent foam protection when having at least one moiety of a threshold size (comprising 4 or more carbon atoms) pendant from a ketal carbon. The carbons in such moieties may be present in one or more chains. The cyclic ketal compounds of the present invention are compatible with foodstuff manufacturing. In particular, it has been discovered that the cyclic ketal compounds of the present invention exhibit excellent foam control performance in both potato and sugar beet processing systems.
