Patent ID: 8895785

Claim:
A process for separating one or more amine byproducts from one or more desired amines comprising the steps of: a) providing a composition comprising i) one or more desired amines selected from alkyleneamines represented by (a) formula (I): wherein x 1 is a number of from 2 to 6, y 1 is a number of from 1 to 6, R 1 represents a hydrogen atom or an alkyl group having 1 to 4 carbon atoms, and R′ 1 represents a group represented by the following formula (1): wherein x′ 1 is a number of from 2 to 6, x″ 1 is 0 or 1 and y′ 1 is a number of from 0 to 4 and formula (II): wherein x 2 and x′ 2 are numbers of from 2 to 6, and R 2 and R′ 2 represent a group represented by the following formula (2): wherein x″ 2 , is a number of from 2 to 6 and y 2 is a number of from 0 to 5, and one or more amine byproducts and ii) a first adjuvant component, wherein the first adjuvant component has a boiling point; b) causing the composition to be subjected to conditions such that at least a portion of the one or more amine byproducts and at least a portion of the first adjuvant component form a byproduct component that has an enhanced separation characteristic relative to the one or more amine byproducts that have not been subjected to said conditions; and c) separating at least a portion of the byproduct component from the composition in the presence of a second adjuvant component.
