abstract
Cyrene is an emerging biobased green solvent that has been shown to have the ability to increase the solubility of hydrophobic substances in water. Even though the water–Cyrene system is an attractive solvent, its applications are hampered by difficulties in the understanding of its solvation mechanism, caused by a delicate chemical equilibrium established between water and Cyrene. This work aims to rationalize the solvent capability of the water–Cyrene system and to establish the mechanisms of solvation through which hydrophobic solutes are dissolved in it. Using the cooperative model of hydrotropy, it is shown that hydrotropy is the solubilization mechanism of hydrophobic solutes in the water–Cyrene system, in most of its concentration range. Furthermore, the ketone form of Cyrene is revealed to be the principal hydrotrope of the system, with the diol form acting as a hydrotrope only at low Cyrene
