Abstract
The present invention relates to separating one or more amine byproducts from one or more desired amines. More particularly, the invention involves forming a byproduct component with one or more amine byproducts and a first adjuvant component. The byproduct component has an enhanced separation characteristic relative to separating the amine byproducts from the desired amines in the absence of an adjuvant. Preferably, the byproduct component is separated in the presence of a second adjuvant component that preferably has a boiling point less than the boiling point of the first adjuvant component.
