✦ Synopsis

We report on preliminary data of the new coexisting phases in the tetrahydrofuran/H 2 O/KCl solution after a certain threshold value of concentration of ions is trespassed ($4 Â 10 À4 mole fraction of KCl in H 2 O). Composition of the discovered phases has been determined by FTIR spectroscopy using Beer-law procedure on H 2 O bending mode (dOH at 1647 cm À1 ). The results are interpreted in terms of ions induced hypercritical point.
