A temperature-regenerated hydrophobic liquid composition includes an extracting molecule of a non-alkaline cationic species, a solvating molecule of a complimentary anionic species and a fluidizing agent. The extracting molecule of a non-alkaline cationic species is a macrocycle of which the ring is formed from 24-32 carbon atoms and has the following formula (I) or (II): wherein -n is an integer ranging from 5 to 8, -p is 1 or 2, -m is 3 or 4, -q and t, which may be identical or different, are 0, 1 or 2, &#x2014;R is a tert-butyl, tert-octyl, O-methyl, O-ethyl, O-propyl, O-isopropyl, O-butyl, O-isobutyl, O-pentyl, O-hexyl, O-heptyl, O-octyl, or OCHPhenyl group or a hydrogen atom, and&#x2014;R' and R&#x2033;, which may be identical or different, are chosen from methyl, ethyl, propyl, isopropyl, butyl, isobutyl, heptyl and octyl groups or R&#x2032; and R&#x2033; together form a pyrrolidine, piperidine or morpholine ring.

Method for extracting salts and temperature-regenerated extracting composition

Disclosed is a method for treating water, including the extraction of at least two ionic species, the ionic species including an anionic species and a cationic species and being present in the water to be treated, the method especially including a step of mixing a liquid hydrophobic organic phase and the water to be treated, the water to be treated being in the liquid state, in order to subsequently obtain liquid treated water and a hydrophobic liquid organic phase loaded with the ionic species, and a step of thermal regeneration of the organic phase loaded with chemical species. Also disclosed are compounds and compositions that can be used in the method.
