“…The gradients increase with the increase of temperature, which reflected that Vm is more sensitive at elevated temperature. The perfect linear relationship between Vm and the mole fraction of water indicates the studied mixtures are ideal solution; similar results have been described for imidazolium ionic liquids by Wang et al 22 .…”

Eutectic ionic liquid (EIL), also called deep eutectic solvent (DES) or ionic liquid analogue (ILA), is a type of ionic solvent prepared from salts and donor molecules 1. In 2003, the deep eutectic phenomenon was first described for a mixture of an organic salt-choline chloride (2-hydroxyethyltrimethylammonium chloride) and a hydrogen bond donor compoundurea (CHCl:Urea) in a 1:2 mole ratio by Abbott et al. 2 , the melting point of the eutectic mixture is 12 °C, which is much lower than either of the individual components. Compared with traditional ionic liquids, this eutectic ionic liquid is low-toxic, easily prepared from industrial bulk materials and sometimes biodegradable, which make it more and more attractive in the area of electrochemistry, material preparation, organic synthesis and isolation process. Except for organic salts, inorganic metal salts (or their hydrate) were confirmed to be effective components of eutectic ionic liquid 3 and the hydrogen bond donors can also be selected from amines 4 , carboxylic acids 5 , amides 6 , alcohol 3 or phenol 3. Among which, the acetamide based eutectic ionic liquids have received especial attention. Acetamide forms eutectic mixture with various compounds for its high solubility with a large number of organic or inorganic compounds 7 and the physicochemical properties of

A series of new N-butylammonium carboxylate ionic liquids (N-butylammonium formate, N-butylammonium acetate, N-butylammonium propionate, and N-butylammonium butyrate) were synthesized by a one-step method and characterized. The thermodynamic properties such as surface tension, density, electrical conductivity, and dynamic viscosity of the ILs were measured as functions of temperature. Important parameters such as molecular volume, crystal energy, thermal expansion coefficient, standard molar entropy, and the surface properties are estimated by the empirical equations. The Vogel−Fulcher−Tamman (VFT) equation is used to explore the dependence of electrical conductivities and dynamic viscosities on temperature. The relationship between the molar conductivity and the fluidity of the ILs was examined through the use of Walden plots. To describe intermolecular interactions of the N-butylammonium carboxylate ILs, the optimized structures and energetics of ILs are calculated by DFT calculations. The calculated energies showed that the increase in the interaction energies between the ion clusters is the same as the trend of experimental viscosities.
