Abstract

See full text

The invention is directed to a method and a system for regenerating an endothermic salt composition from an aqueous solution thereof, said method comprising a) contacting a switchable-polarity compound with the aqueous solution of the endothermic salt composition to obtain a raffinate phase and an extract phase, wherein the raffinate phase comprises said endothermic salt composition in a higher concentration than said aqueous solution and said extract phase comprises the switchable-polarity compound and water; and b) separating the raffinate phase and the extract phase into a separated raffinate and a separated extract. The endothermic salt can be used in systems for cooling food, milk, medicines and/or air.
