Abstract
The invention provides a process for regenerating a liquid absorbent, including: contacting the liquid absorbent with a hydrophobic medium, wherein the liquid absorbent includes at least one amine of Formula (I) and degradation product thereof including at least one imine of Formula (II), wherein each Ar is independently an aromatic group and each R is independently selected from hydrogen, an organyl group and NH2; and selectively extracting the degradation product into or through the hydrophobic medium.

A process for regenerating a liquid absorbent, comprising:
- contacting the liquid absorbent with a hydrophobic medium, wherein the liquid absorbent comprises at least one amine of Formula (I) and degradation product thereof comprising at least one imine of Formula (II):
- wherein each Ar is independently an aromatic group and each R is independently selected from hydrogen, an organyl group and NH2;
- and
- selectively extracting the degradation product into or through the hydrophobic medium.
