Abstract

The present invention provides a process of extracting an aminoalkane from an aminoalkane-containing aqueous feed (5) comprising (a) contacting (7) the aqueous feed (5) with a depleted solvent comprising an alkylated phenol to obtain a first extract (12) enriched in aminoalkane and a first raffinate (2) having a reduced aminoalkane-content; (b) contacting (15) the first extract (12) with an expelling agent (17) and sufficient water (20) to dissolve the expelled aminoalkane to obtain a second extract enriched in aminoalkane (22) and a second raffinate including the expelling agent (25); (c) withdrawing the second extract (22) from the second raffinate (25) to obtain an aqueous product stream enriched in aminoalkane (22); and (d) removing expelling agent (39) from the second raffinate (25) to obtain the depleted solvent (9) for use in step (a).
