A process for the separation of naphthalenesulfonate-based carbonyl condensates from water is provided. The process comprises contacting a mixture comprised of water and a naphthalenesulfonate-based carbonyl condensate (preferably a material selected from the group consisting of formaldehyde condensates of naphthalenesulfonic acids, formaldehyde condensates of lower-alkyl substituted naphthalenesulfonic acids, and mixtures of two or more of such materials) with a liquid organic phase comprised of a cationic lipophilic amine to form an aqueous phase depleted with respect to said mixture of naphthalenesulfonate-based carbonyl condensate and a liquid organic phase enriched in naphthalenesulfonate-based carbonyl condensate. The process further comprises separating said aqueous phase depleted with respect to said mixture of naphthalenesulfonate-based carbonyl condensate and said liquid organic phase enriched with respect to naphthalenesulfonate-based carbonyl condensate. The liquid organic phase can then be stripped with an alkaline stripping solution to regenerate the cationic lipophilic amine.
