Chapter 13 discusses the design and analysis of the microscopic features of binary solvent systems formed by room temperature ionic liquids (RTILs) with molecular solvents. For this purpose, protic ionic hquids (PILs), ethylammoiuum nitrate (FAN), and l-n-butyl-3-methylimidazolium (bmim)-based ILs and the molecular solvents such as acetonitrile, dimethyl sulfoxide, A,A-dimethylfonnamide, and protic (different alcohols) are selected. The study focuses on the identification of solvent mixtures of relevant solvating properties to propose them as new solvents. ...

Ionic Liquids as Binary Mixtures with Selected Molecular Solvents. 

With the aim of completing this stndy, we analysed the microscopic features of solvent systems resulting from the basis of binary mixtures formed by a protic molecular solvent (MeOH, ethanol (EtOH), propan-l-ol, propan-2-ol or 2-elhoxy-ethanol (EtOEtOH)) and a bmim-based ionic liquid cosolvent composed of different anions [BE ], [PE ], chloride [Cl] and bromide [Br]. The selection of these molecular solvents was done mainly on the basis of their HBD capacity. At the same time, it was conveiuent to discuss the incidence of anion type on the solvation pattern. 

In general, for the proposed new solvents , it can be observed that the dipolarity/ polarisability and basicity are similar to those of AN and DMF. The acidity is quite different being highly increased, particularly in the case of AN. In relation to the protic solvent + imidazolium-based ILs binary solvent mixtures, the compositions of the mixtures are dependent on both the nature of the protic solvent as well as on the anion type of the ionic liquid. With ethanol and 2-ethoxyethanol as molecular solvents, the IL displays large solubility, particularly when the anions are [BF ] or [Cl]. The ILs [bmim][PF ] and [bmim][Br] exhibit the lowest solubility, so their mixtures were explored at the smallest range of compositions.

The glass-formers include molecular liquids and amorphous polymers of diverse chemical structures, room temperature ionic liquids, and binary mixtures of two van der Waals liquids" or two amorphous polymers. All show the property of temperature-pressure superpositioning of the frequency dispersion of the structural cr-relaxation at constant r .
