Thermodynamic behavior of [OMIM]-based ionic liquid and H2O systems: Experimental, model prediction and mechanism insights

The vapor pressures of the binary systems (water + [OMIM][BF4], water + [OMIM][Tf2N], and water + [OMIM][PF6]) were measured by a modified equilibrium still at temperatures ranging from 323.15 to 358.15 K and water mole fraction ranging from 0.1 to 0.9 for water + [OMIM][BF4], from 0.1 to 0.4 for water and [OMIM][Tf2N] and from 0.05 to 0.45 for water + [OMIM][PF6] binary systems, respectively. The experimental results indicate that with the...
