The present invention provides a process for the recovery of solutes from a first aqueous solution comprising equilibrating said first aqueous solution with a first low water miscibility solvent at a temperature higher than room temperature so as to form at least one second solvent phase that is water-rich and low in solutes, and a second further optionally aqueous phase containing said solutes, wherein the temperature of the solutes-water-solvent system is adjusted to a zone of the system, defined as the inversion distribution temperature zone, lying between 30°C below the CST of said water-solvent system and 5O°C above the CST of said system, characterized in that said second solvent phase is separated from said second further phase and cooled to induce at least one separation of a third aqueous phase and a third solvent phase from said second solvent phase and wherein solvent from said third solvent phase is recycled for equilibration with said first aqueous phase.
