Abstract

A surprising mixed solvent effect, both in its magnitude and direction, has been found in the phase diagram of the ternary mixture of ([C₄mim][PF₆] + (water + ethanol)). For a molar ratio of 1:1 of water to ethanol, the co-solvent effect in the near-critical demixing temperature can be as large as 80 K.
