Abstract

Separation of small, hydrophilic molecules from aqueous solutions on one side, and dissolution of hydrophobic organic molecules in water on the other, are nowadays among the most difficult challenges in chemical and bio-technology. Even though these two tasks are seemingly of opposite nature, it is demonstrated herein that both processes can be facilitated by addition of zwitterionic salts, a new class of compounds, which can act either as solubility enhancers or phase separation promoters depending on structure of solute dissolved in an aqueous solution. At a more fundamental level, this study investigates salting in/out propensity of the ions and supports importance of both salt - solute interaction and their concentration.
